The least common multiple (LCM) of 13 and 65 is the smallest multiple that both numbers share. To find the LCM, you can use the formula LCM(a, b) = (|a * b|) / GCD(a, b), where GCD is the greatest common divisor. In this case, the GCD of 13 and 65 is 13, so the LCM is (|13 * 65|) / 13 = 65.

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
The LCM of 65 and 100 is 1300.
LCM of two numbers = product/HCF; 65 = 5 x 13, 155 = 5 x 31 so HCF is 5 and LCM is 65 x 155/5 = 2015
The LCM is: 1,560
