factorization: 78=2*3*13 65=5*13 LCM=2*3*5*13=390
65
The LCM is: 65
lcm(54, 65) = 3510 54 = 2 x 33 65 = 5 x 13 lcm = 2 x 33 x 5 x 13 = 3510
The GCF is 1 and the LCM is 65.
325
Prime Factorization of: 130= 2 x 5 x 13 65 = ......5 x 13 ============= LCM= 2 x 5 x 13 = 130
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 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.
39: 3 x 13 65: 5 x 13 So the LCM is 3 x 5 x 13 = 195
They are: GCF = 5 and LCM = 325 and the sum is 5+325 = 330
The greatest common factor of 30 and 65 is 5.5 x 6 = 305 x 13 = 65
