Factors of 65
Students need to understand that factors are the building blocks of numbers, and it 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 65?
The factors of 65 will be 1, 5, 13, and 65. These are the only numbers which divide 65 evenly without leaving any remainder. And, it always will be in a whole number. These are the only numbers that divide 65 exactly.
Negative Factors of 65 : Negative Factors of 65 are 1, 5, 13, and 65.
Prime Factors of 65: 5 and 13
Prime Factorization of 65: It is expressed as 5×13
The Sum of Factors of 65: The sum of factors of 65 is 1 + 5 + 13 + 65 =84
How to Find the Factors of 65
To find the factors of 65, 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 number from 2 up to the square root of the number.
Step 2: To each number, find its pair.
1×65 =65
5×13 =65
6, 7 do not divide 65 evenly.
Therefore, the factors of 65 are 1, 5, 13, and 65.
This method is a process of systematically multiplying different numbers to get the original number.
Finding Factors by Division Method
If children 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 65, where the square root of 65 is ±8.06. So, you need to check until 8.
65 / 1 = 65, both 1 and 65 are factors.
65 / 5 = 13, both 5 and 13 are factors
65 / 6, 7, 8 won’t result in whole number.
Then, the factors of 65 will be 1, 5, 13, and 65.
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 65 = 5 and 13
Prime Factorization of 65 = 5×13
Factor Tree
A factor tree is a visual representation of the prime factorization of a number.
= 5 and 15 are the prime building blocks of 65.
Factor Pairs: A factor pair is a combination of two numbers that multiply together to result in a specific value.
Factor a pair of number of 65 = 1 and 65 = 1×65 =65
= 5 and 13 = 5×13 =65
The above numbers are the factor pair for 65, as 65 only holds a few divisors.
Positive Pair Factors =1 and, 65, 5 and 13
Negative Pair Factors = -1 and -65, -5 and -13
Common Mistakes and How to Avoid Them in Factors of 65
Students might make mistakes while finding the factors. Understand the common errors that can occur at the time of calculation
Mistake 1
Making mistake on odd number
Students used to think that 65 will be an odd number and won’t check with divisibility by 2. To overcome this issue, be clear if the number is even or odd and check it is divisibility by 2.
Factors of 65 examples
Problem 1
Determine whether 65 is divisible by 7?
65 is divisible by 7.
Explanation
Check divisible by 7, divide 65 by 7.
65 / 7 = 9.286
Since the result is not an integer, 65 is not divisible by 7.
Problem 2
Find the sum of the digits of the number 65.
The sum of the digits of 65 is 11
Explanation
The digits of 65 are 6 and 5.
Add the digits : 6 + 5 =11
Thus, the sum of the digits of 65 is 11.
Problem 3
Find the least Common Multiple (LCM) and the Greatest Common Divisor of 65 and 52.
The GCD of 65 and 52 is 13, and the LCM is 260.
Explanation
Find prime factorization
65 = 5×13
52 = 2×2×13
GCD is the product of common prime factors = 13
LCM is the product of the highest powers of all prime factors.
LCM = 2×2×5×13 =260
