What are the factors of 36 is the question that arises while dealing with factors of a number to be found. This can be achieved by using different methods like multiplication, division, and prime factorization.
What are the Factors of 36?
Factors of 36 are the numbers that exactly divide 36 leaving the remainder zero. In simple words, it can be said if two numbers when multiplied give the product as 36 then the numbers are called factors of 36.
Factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18 and 36.
Let’s pick a number called 3 from above
- 36 ÷ 3 = 12
- Here quotient = 12 and remainder = 0
- If we multiply 12 and 3 product is 12 × 3 = 36
- Therefore, 12 and 3 are factors of 36
How to find factors of 36 using different methods
There are different methods to find factors of a number. By applying any of these methods it can be easy to find the factors of 36
Multiplication method
In the multiplication method, we consider the numbers which when multiplied in pairs results to 36
Let’s see the multiplication process
1 × 36 = 36
2 × 18 = 36
3 × 12 = 36
4 × 9 = 36
6 × 6 = 36
9 × 4 =36 (Product repeats in reverse order multiplication )
So the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
Division method
In the division method, we consider the numbers which exactly divide 36 with leaving a remainder.
Lets see the division process
36 ÷ 2 = 18
36 ÷ 3 = 12
36 ÷ 4 = 9
36 ÷ 6 = 6
36 ÷ 9 = 4
36 ÷ 12 = 3
36 ÷ 18 = 2
As 1 and itself are factors of any number 1 and 36 are also factors of 36
There all the numbers 1, 2, 3, 4, 6, 9, 12, and 36 are factors of the number 36.
How to find factors of 36 by prime factorization method
In the prime factorization method, we consider the numbers written as a product of prime factors as prime factors of 36.
The following steps help in finding the prime factors of a number
Step1: Divide the given number 36 by the least prime number (2).
36 ÷ 2 = 18
Step2: If the resultant number is not divisible by this number (2) then, divide it using the next least prime number(3).
18 ÷ 2 = 9
Step3: As the resultant number 9 is not divisible by 2 we divide it by 3.
9 ÷ 3 = 3
Step4: If the resultant number is not divisible by 3 divide it using the next least prime number 5.
3 ÷ 3 = 1
Considering all the above steps the prime factors of 36 are 2 × 2 × 3 × 3 => 2² × 3².
The prime factors of 36 are 2 × 2 × 3 × 3 => 2² × 3².
Factors of 36 in pairs and product form
From above, we know if the product of a pair of numbers is equal to 36 then the numbers are factors of 36. As the product of two negative numbers is positive there can be negative factors for the number 36. Thus we have a positive pair of factors of 36 and a negative pair of factors of 36.
