Factors are the numbers that divide any given number evenly without a 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 771, how they are used in real life, and tips to learn them quickly.
The numbers that divide 771 evenly are known as factors of 771.
A factor of 771 is a number that divides the number without a remainder.
The factors of 771 are 1, 3, 257, and 771.
Negative factors of 771: -1, -3, -257, and -771.
Prime factors of 771: 3 and 257.
Prime factorization of 771: 3 × 257.
The sum of factors of 771: 1 + 3 + 257 + 771 = 1032
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 771. Identifying the numbers which are multiplied to get the number 771 is the multiplication method.
Step 1: Multiply 771 by 1, 771 × 1 = 771.
Step 2: Check for other numbers that give 771 after multiplying 3 × 257 = 771
Therefore, the positive factor pairs of 771 are: (1, 771) and (3, 257). All these factor pairs result in 771.
For every positive factor, there is a negative factor.
Dividing the given numbers 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 a simple division method
Step 1: Divide 771 by 1, 771 ÷ 1 = 771.
Step 2: Continue dividing 771 by the numbers until the remainder becomes 0.
771 ÷ 1 = 771
771 ÷ 3 = 257
Therefore, the factors of 771 are: 1, 3, 257, 771.
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 771 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
771 ÷ 3 = 257
257 is a prime number and cannot be divided further.
The prime factors of 771 are 3 and 257.
The prime factorization of 771 is: 3 × 257.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 771 is divided by 3 to get 257.
Here, 257 is a prime number and cannot be divided anymore.
So, the prime factorization of 771 is: 3 × 257.
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 771: (1, 771) and (3, 257).
Negative factor pairs of 771: (-1, -771) and (-3, -257).
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 friends and 771 marbles. How will they divide it equally?
They will get 257 marbles each.
To divide the marbles equally, we need to divide the total marbles with the number of friends.
771/3 = 257
A parking area is rectangular, the length of the area is 3 meters and the total area is 771 square meters. Find the width?
257 meters.
To find the width of the area, we use the formula,
Area = length × width
771 = 3 × width
To find the value of width, we need to shift 3 to the left side.
771/3 = width
Width = 257.
There are 257 gift bags and 771 candies. How many candies will be in each bag?
Each bag will have 3 candies.
To find the candies in each bag, divide the total candies with the bags.
771/257 = 3
In a class, there are 771 students, and 3 groups. How many students are there in each group?
There are 257 students in each group.
Dividing the students with the total groups, we will get the number of students in each group.
771/3 = 257
771 books need to be arranged in 3 shelves. How many books will go on each shelf?
Each of the shelves has 257 books.
Divide total books with shelves.
771/3 = 257
