When their GCF is greater than 1. When they have prime factors in common.
4 and 6 6 and 8 Any time the two numbers have a common factor, their LCM will be less than the product because the common factor contributes to the LCM fewer times than it contributes to the product.
4 and 9 7 and 8
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78. Need to know how to get the answer
Pairs with common factors other than 1.
All of the composite numbers less than 100 have factor pairs.
The product of the prime numbers less than 100 is 2.3055679639455188e+36
If their GCF is 1, their LCM is their product. If their GCF is greater than 1, their LCM is less than their product.
No. The product of two negative numbers is positive.
If the two numbers have no common factors other than 1, the LCM will be their product. If there are other common factors, the LCM will be less.
No, the product of two positive mixed numbers can never be less than one.
Eight pairs.
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
