What are Factors of 1200?
Factors of 1200 are pairs of those numbers whose products result in 1200. These factors are either prime numbers or composite numbers.
How to Find the Factors of 1200?
To find the factors of 1200, we will have to find the list of numbers that would divide 1200 without leaving any remainder.
- 1200/150 = 8; therefore, 150 is a factor of 1200 and 8 is also a factor of 1200.
- 1200/400 = 3; therefore, 400 is a factor of 1200 and 3 is also a factor of 1200.

Factors of 1200 by Prime Factorization
- 1200 ÷ 2 = 600
- 600 ÷ 2 = 300
- 300 ÷ 2 = 150
- 150 ÷ 2 = 75
Further dividing 75 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 75 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 1200 can be written as 24 × 31 × 52 where 2, 3, 5 are prime.

Example 1: How many factors are there for 1200?
Solution:
The factors of 1200 are too many, therefore if we can find the prime factorization of 1200, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 1200 = 24 × 31 × 52
Therefore, the total number of factors are (4 + 1) × (1 + 1) × (2 + 1) = 5 × 2 × 3 = 30 -
