WebThe Least Common Multiple (LCM) of two relatively prime numbers is always equal to their product. For example: LCM of 4 and 5 (relatively prime numbers) = 20. If n is a prime number, then all integers less than or equal to n are relatively prime to n. If a and b are two relatively prime numbers, then a + b is relatively prime to a × b. WebThe two numbers which have only 1 as their common factor are called co-primes. For example, Factors of 5 are 1,5 Factors of 3 are 1,3 Common factors is 1. So they are co …

WebCompare this to two non-prime numbers: 4 and 6. The prime factors of 4 are 2 and 2, the prime factors of 6 are 2 and 3. So the least common multiple will be the maximum number of factors of 2 (that's two) and the maximum number of factors of 3 (that's one). So it is 2 x 2 x 3 = 12. For a harder example, consider 84 and 315. What is their LCM? WebCo-primes are a pair of numbers whose common factor comprises only 1.
