Factors of 1944 by Prime Factorization
- 1944 ÷ 2 = 972
- 972 ÷ 2 = 486
- 486 ÷ 2 = 243
Further dividing 243 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 243 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 1944 can be written as 23 × 35 where 2, 3 are prime.

Example 1: How many factors are there for 1944?
Solution:
The factors of 1944 are too many, therefore if we can find the prime factorization of 1944, 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 1944 = 23 × 35
Therefore, the total number of factors are (3 + 1) × (5 + 1) = 4 × 6 = 24 -
