Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 705, how they are used in real life, and the tips to learn them quickly.
The numbers that divide 705 evenly are known as factors of 705.
A factor of 705 is a number that divides the number without remainder.
The factors of 705 are 1, 3, 5, 15, 47, 141, 235, and 705.
Negative factors of 705: -1, -3, -5, -15, -47, -141, -235, and -705.
Prime factors of 705: 3, 5, and 47.
Prime factorization of 705: 3 × 5 × 47.
The sum of factors of 705: 1 + 3 + 5 + 15 + 47 + 141 + 235 + 705 = 1,152
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 705. Identifying the numbers which are multiplied to get the number 705 is the multiplication method.
Step 1: Multiply 705 by 1, 705 × 1 = 705.
Step 2: Check for other numbers that give 705 after multiplying
3 × 235 = 705
5 × 141 = 705
15 × 47 = 705
Therefore, the positive factor pairs of 705 are: (1, 705), (3, 235), (5, 141), and (15, 47).
All these factor pairs result in 705. For every positive factor, there is a negative factor.
Dividing the given numbers with the 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 a simple division method -
Step 1: Divide 705 by 1, 705 ÷ 1 = 705.
Step 2: Continue dividing 705 by the numbers until the remainder becomes 0.
705 ÷ 1 = 705
705 ÷ 3 = 235
705 ÷ 5 = 141
705 ÷ 15 = 47
Therefore, the factors of 705 are: 1, 3, 5, 15, 47, 141, 235, 705.
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 705 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
705 ÷ 3 = 235
235 ÷ 5 = 47
47 ÷ 47 = 1
The prime factors of 705 are 3, 5, and 47.
The prime factorization of 705 is: 3 × 5 × 47.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 705 is divided by 3 to get 235.
Step 2: Now divide 235 by 5 to get 47.
Step 3: Here, 47 is a prime number, that cannot be divided anymore.
So, the prime factorization of 705 is: 3 × 5 × 47.
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 705: (1, 705), (3, 235), (5, 141), and (15, 47).
Negative factor pairs of 705: (-1, -705), (-3, -235), (-5, -141), and (-15, -47).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 3 teams and 705 points. How will they divide it equally?
They will get 235 points each.
To divide the points equally, we need to divide the total points with the number of teams.
705/3 = 235
A garden is rectangular, the length of the garden is 47 meters and the total area is 705 square meters. Find the width?
15 meters.
To find the width of the garden, we use the formula,
Area = length × width
705 = 47 × width
To find the value of width, we need to shift 47 to the left side.
705/47 = width
Width = 15.
There are 5 boxes and 705 marbles. How many marbles will be in each box?
Each box will have 141 marbles.
To find the marbles in each box, divide the total marbles with the boxes.
705/5 = 141
In a school, there are 705 students, and 47 classes. How many students are there in each class?
There are 15 students in each class.
Dividing the students with the total classes, we will get the number of students in each class.
705/47 = 15
705 chairs need to be arranged in 5 rows. How many chairs will go in each row?
Each of the rows has 141 chairs.
Divide total chairs with rows.
705/5 = 141
