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
To find the least common multiple (LCM) of 65 and 104, we first need to find the prime factorization of each number. The prime factorization of 65 is 5 x 13, and the prime factorization of 104 is 2^3 x 13. To calculate the LCM, we take the highest power of each prime factor that appears in either factorization, which gives us 2^3 x 5 x 13 = 520. Therefore, the least common multiple of 65 and 104 is 520.
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 LCM is 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
