Factors of 51
Students need to understand that factors are the building blocks of numbers, and understanding factors is essential in various mathematical concepts. When you are sharing money equally among a group of people, factors are used to resolve the fair distribution.
What are the Factors of 51?
The factors of 52 will be 1, 3, 17, 51. These are the only numbers which divide 51 evenly without leaving any remainder. And, it always will be in a whole number. These are the only numbers that divide 51 exactly.
Negative Factors of 51: Negative Factors of 51 are -1, -3, -17, -51.
Prime Factors of 51 : 3 and 17
Prime Factorization of 51 : It is expressed as 3×17
The sum of Factor of 51 : The sum of factors of 51 is 1+3+17+51 =72
How to Find the Factors of 51
To find the factors of 51, students need to divide the original number evenly without leaving a remainder. Some methods are explained below for easy solution of factors-
- Multiplication Method
- Division Method
- Prime Factor and Prime Factorization
- Factor Tree
Finding Factors Using Multiplication Method
Students need to find pairs of numbers that multiply together to give the original number.
Step 1: Check numbers from 2 up to the square root of the number.
Step 2: To each number, find its pair.
1×51 =51
3×17 =51
17×3 =51
51×1 =51
The above are the factors of 51 are 1, 3, 17, 51.
This method is a process of systematically multiplying different numbers to get the original number.
Finding Factors of 51 by Division Method
If children need to get the division in a whole number, then both the divisor and the quotient are factors.
Check numbers from 2 up to the square root of 51, where the square root of is 7.14. So, you need to check until 7.
51 / 1 = 51, both 1 and 51 are factors.
51 / 3 = 17, both 3 and 17 are factors.
51 / 4, 5, 6, 7 won’t result in whole numbers.
Then, the factors of 51 will be 1, 3, 17,and 51.
Prime Factors and Prime Factorization
Prime factors are the numbers that divide a given number evenly without a remainder. And, prime factorization is the process of breaking down a number into its prime factors.
Prime Factors of 51 = 3 and 17
Prime Factorization of 51 = 3×17
Factor Tree:
A factor tree is a visual representation of the prime factorization of a number.
= 3 and 17 are the prime building blocks of 51.
Factor Pairs: A factor pair is a combination of two numbers that multiply together to result in a specific value.
Factor a pair of numbers 51 = 1 and 51 =1×51 =51
= 3 and 17 =3×17 =51
The above numbers are the factor pairs for 51, as 51 only holds a few divisors.
Positive Pair Factors = 1 and 51, 3 and 17
Negative Pair Factors = -1 and -51, -3 and -17
