You had me until "product." The product of 4 digits can't be prime.

The LCM of two numbers is the product of the numbers if one of the numbers is a prime. Since 11 is a prime, the LCM of 10 and 11 is 110 (10 x 11). If neither number had been a prime, the LCM would have been the product of all the prime factors of the numbers to their greatest power.

to find a product of prime factors lets say you have 108 and you have to find the product of prime factors you should divide by 2 and then find the answer so 54, 54 isn't prime so you keep goin until the 2 numbers are prime and then you put down the prime numbers with a times in between. heather age 12
