Factors of 785
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 785, how they are used in real life, and tips to learn them quickly.
What are the Factors of 785?
The numbers that divide 785 evenly are known as factors of 785.
A factor of 785 is a number that divides the number without remainder.
The factors of 785 are 1, 5, 157, and 785.
Negative factors of 785: -1, -5, -157, and -785.
Prime factors of 785: 5 and 157.
Prime factorization of 785: 5 × 157.
The sum of factors of 785: 1 + 5 + 157 + 785 = 948
How to Find Factors of 785?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using division method
- Prime factors and prime factorization
Finding Factors Using Multiplication
To find factors using multiplication, identify the pairs of numbers that are multiplied to give 785. Identifying the numbers which are multiplied to get the number 785 is the multiplication method.
Step 1: Multiply 785 by 1, 785 × 1 = 785.
Step 2: Check for other numbers that give 785 after multiplying 5 × 157 = 785
Therefore, the positive factor pairs of 785 are: (1, 785) and (5, 157).
All these factor pairs result in 785. For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given number with whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following the simple division method:
Step 1: Divide 785 by 1, 785 ÷ 1 = 785.
Step 2: Continue dividing 785 by the numbers until the remainder becomes 0.
785 ÷ 1 = 785
785 ÷ 5 = 157
Therefore, the factors of 785 are: 1, 5, 157, 785.
Prime Factors and Prime Factorization
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
- Using prime factorization
- Using factor tree
Using Prime Factorization: In this process, prime factors of 785 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
785 ÷ 5 = 157
157 ÷ 157 = 1
The prime factors of 785 are 5 and 157.
The prime factorization of 785 is: 5 × 157.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show:
Step 1: Firstly, 785 is divided by 5 to get 157.
Step 2: 157 is a prime number and cannot be divided further. So, the prime factorization of 785 is: 5 × 157.
Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs.
Both positive and negative factors constitute factor pairs.
Positive factor pairs of 785: (1, 785) and (5, 157).
Negative factor pairs of 785: (-1, -785) and (-5, -157).
Common Mistakes and How to Avoid Them in Factors of 785
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
People might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every number. Always remember to include 1 and the number itself.
For example, in factors of 785, 1 and 785 are also factors.
Mistake 2
Missing Negative Factors
We tend to mention only positive factors. There are also negative factors; always check whether you have mentioned negative factors.
For example, the factors of 785 include -1, -5, -157, etc.
Mistake 3
Including Fractions
People might sometimes add fractions as a factor. Only whole numbers can be a factor.
For example, thinking 2.5 as a factor, because 785/2.5 = 314, and it is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes.
For example, thinking all the factors of 785 are prime numbers.
For example, 5 and 157 are the prime factors of 785, but it has other factors like 1, 785.
Mistake 5
Mistake in Factorization
People might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 785 as 5 × 157 and missing all the key factors.
Factors of 785 Examples
Problem 1
A bakery has 785 cupcakes. If they want to pack them into boxes of 5, how many boxes will they need?
They will need 157 boxes.
Explanation
To find out how many boxes are needed, divide the total cupcakes by the number of cupcakes per box.
785/5 = 157
Problem 2
A rectangular garden has a length of 157 meters and an area of 785 square meters. Find the width.
5 meters.
Explanation
To find the width of the garden, use the formula,
Area = length × width
785 = 157 × width
To find the value of the width, divide 785 by 157.
785/157 = width
Width = 5.
Problem 3
A company has 785 products to ship. If each carton can hold 785 products, how many cartons are needed?
1 carton is needed.
Explanation
To find the cartons needed, divide the total products by the carton capacity.
785/785 = 1
Problem 4
A school is planning a trip for 785 students and they want to split them into groups of 5. How many groups will there be?
There will be 157 groups.
Explanation
Dividing the students into groups, we will get the number of students in each group.
785/5 = 157
Problem 5
785 chairs need to be arranged in 157 rows. How many chairs will be in each row?
Each row will have 5 chairs.
Explanation
Divide total chairs by rows.
785/157 = 5
