Learn what prime factors are with examples and their importance in math and computer science.

17 views

A prime factor in mathematics is a factor of a number that is a prime number. For example, the prime factors of 12 are 2 and 3 because 2 and 3 are prime numbers and they can multiply to give 12 (2×2×3 = 12). Prime factors are critical in various fields of mathematics and computer science, particularly in number theory and cryptography.**
