The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.
The LCM of 12 and 13 is 156.
Their product.
LCM(12, 13, 18) = 468
Their product.
The numbers are prime so their LCM is their product.ie LCM(13,17) = 13*17 = 221Their product.
They only have a common factor of one(1), so the product of 13 & 15 is the same as the LCM. 195
The LCM of 12 and 13 is 156. Since there are no factors other than 1 common to 12 and 13 then the LCM is the product of the two numbers. 12x13=156
The LCM of 12 and 13 is 156.
The LCM of 12 and 13 is 12 * 13 / GCF(12,13) = 156.

The LCM is: 390
LCM(12, 13, 18) = 468
13 is prime. The LCM will therefore have to be the product of these two numbers.
