What Are the Factors of 150?
The factors of 150 are the numbers that on dividing 150 leave no remainder. Since 150 is a composite number, it will have more than two factors. The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150.
How to Calculate the Factors of 150?
Let us calculate the factors of 150.
When considering numbers that can divide 150 without remainders, we start with 1, then check 2, 3, 4, 5, 6, 7, 8, 9, etc. up to 75 (which is exactly half of 150).
Division
Remainder
150/1 gives remainder 0 hence, 1 is a factor 150/2 gives remainder 0 hence, 2 is a factor 150/3 gives remainder 0 hence, 3 is a factor 150/5 gives remainder 0 hence, 5 is a factor 150/6 gives remainder 0 hence, 6 is a factor 150/10 gives remainder 0 hence, 10 is a factor 150/15 gives remainder 0 hence, 15 is a factor 150/25 gives remainder 0 hence, 25 is a factor 150/30 gives remainder 0 hence, 30 is a factor 150/50 gives remainder 0 hence, 50 is a factor 150/75 gives remainder 0 hence, 75 is a factor 150/150 gives remainder 0 hence, 150 is a factor
Hence, the factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150.

Prime factorization of a number refers to representing a number in the form of the product of its prime factors. Prime factors of any number can be found using the following methods.
Method 1: Division method
Now let us find the prime factors of 150 by division method. Divide the number 150 with the smallest prime number, i.e. 2.
150/2 = 75
Again, divide 75 by 2.
75/2 = 37.5
This cannot be a factor, so moving to the next prime number.
75/3 = 25
Again, divide 25 by 3.
25/3 = 8.333
Now, if we divide 25 by 3 we get a fraction number, which cannot be a factor. Now, proceed to the next prime numbers, i.e. 5.
25/5 = 5

Again, divide 5 by 5.
5/5 = 1
We get 1 at the end and we cannot further proceed with the division method.
So, the prime factorization of 150 is 2 x 3 x 5 x 5 = 2 x 3 × 52 where 2, 3, and 5 are the prime numbers.
Method 2: Factor tree
The prime factors of 150 are: 150 = 2 x 3 x 52
Further, find the products of the multiplicands in different orders to obtain the composite factors of the number. Thus, the factors can be written including both prime and composite numbers as 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150
The product of two negative numbers is a positive number. The pair factors having negative factors are called negative pair factors.
The negative pair factors of 150 are, (-1, -150), (-2, -75), (-3, -50), (-5, -30), (-6, -25), (-10, -15).
Important Notes:
- Only whole numbers and integers can be factors.
- Only composite numbers can have more than two factors.
