What are Factors of 504?
Factors of 504 are pairs of those numbers whose products result in 504. These factors are either prime numbers or composite numbers.
How to Find the Factors of 504?
To find the factors of 504, we will have to find the list of numbers that would divide 504 without leaving any remainder.
 504/12 = 42; therefore, 12 is a factor of 504 and 42 is also a factor of 504.
 504/126 = 4; therefore, 126 is a factor of 504 and 4 is also a factor of 504.

Factors of 504 by Prime Factorization
 504 ÷ 2 = 252
 252 ÷ 2 = 126
 126 ÷ 2 = 63
Further dividing 63 by 2 gives a nonzero remainder. So we stop the process and continue dividing the number 63 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 504 can be written as 2^{3} × 3^{2} × 7^{1} where 2, 3, 7 are prime.

Factors of 504 Solved Examples

Example 1: How many factors are there for 504?
Solution:
The factors of 504 are too many, therefore if we can find the prime factorization of 504, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is a^{x} × b^{y} × c^{z} 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 504 = 2^{3} × 3^{2} × 7^{1}
Therefore, the total number of factors are (3 + 1) × (2 + 1) × (1 + 1) = 4 × 3 × 2 = 24 
Example 2: Find the Least Common Multiple (LCM) and Greatest Common Divisor (GCD) of 504 and 463.
