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 781, how they are used in real life, and tips to learn them quickly.
The numbers that divide 781 evenly are known as factors of 781.
A factor of 781 is a number that divides the number without remainder.
The factors of 781 are 1, 11, 71, and 781.
Negative factors of 781: -1, -11, -71, and -781.
Prime factors of 781: 11 and 71.
Prime factorization of 781: 11 × 71.
The sum of factors of 781: 1 + 11 + 71 + 781 = 864
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 781. Identifying the numbers which are multiplied to get the number 781 is the multiplication method.
Step 1: Multiply 781 by 1, 781 × 1 = 781.
Step 2: Check for other numbers that give 781 after multiplying 11 × 71 = 781
Therefore, the positive factor pairs of 781 are: (1, 781) and (11, 71).
All these factor pairs result in 781.
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 simple division method
Step 1: Divide 781 by 1, 781 ÷ 1 = 781.
Step 2: Continue dividing 781 by the numbers until the remainder becomes 0.
781 ÷ 1 = 781
781 ÷ 11 = 71
781 ÷ 71 = 11
Therefore, the factors of 781 are: 1, 11, 71, and 781.
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 781 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
781 ÷ 11 = 71
71 ÷ 71 = 1
The prime factors of 781 are 11 and 71.
The prime factorization of 781 is: 11 × 71.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 781 is divided by 11 to get 71.
Step 2: Now divide 71 by 71 to get 1. Here, 71 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 781 is: 11 × 71.
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 781: (1, 781) and (11, 71).
Negative factor pairs of 781: (-1, -781) and (-11, -71).
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 11 friends and 781 candies. How will they divide it equally?
They will get 71 candies each.
To divide the candies equally, we need to divide the total candies with the number of friends.
781/11 = 71
A field is rectangular, the length of the field is 71 meters and the total area is 781 square meters. Find the width?
11 meters.
To find the width of the field, we use the formula
Area = length × width
781 = 71 × width
To find the value of width, we need to shift 71 to the left side.
781/71 = width
Width = 11.
There are 71 bags and 781 candies. How many candies will be in each bag?
Each bag will have 11 candies.
To find the candies in each bag, divide the total candies with the bags.
781/71 = 11
In a class, there are 781 students, and 11 groups. How many students are there in each group?
There are 71 students in each group.
Dividing the students with the total groups, we will get the number of students in each group.
781/11 = 71
781 books need to be arranged in 11 shelves. How many books will go on each shelf?
Each of the shelves has 71 books.
Divide total books with shelves.
781/11 = 71
