1 and 5 have an LCM of 5.

Any pair of prime numbers. 5 and 7 11 and 13

The LCM of 5 and 6 is 30.

4 and 5.

LCM is the multiple of the highest power of prime factors of two or more numbers. Since prime numbers have no other factors than themselves, the LCM of two or more prime numbers is their product. As an example, the LCM of 3, 5, and 53 is 3 x 5 x 53 = 795.

Find the LCM by finding prime factorization of both numbers:100 = 2 * 2 * 5 * 5130 = 2 * 5 * 13Then, count each pair of prime numbers. The two factorizations have two pairs of prime numbers: one pair of 2's and one pair of 5's (pairs are bolded, above):Paired primes: 2, 5Next, count the remaining primes and multiply them with the paired primes.Paired primes: 2, 5Unpaired primes: 2, 5, 13The LCM of 100 and 130 is2 * 2 * 5 * 5 * 13 = 1300

2 squared 3 squared 5 or 180

Prime number of 13 is 13 Prime numbers of 26 are 2 and 13 Prime numbers of 65 are 5 and 13 LCM = 2*5*13 =130

5 and 75 15 and 25

5 and 75

2 and 5 are one such pair.

40 is the LCM of 5 and 8. If two numbers are relatively prime ( have no divisors in common, the LCM is just their product. )
