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.

Prime numbers are used to find the product of the prime factors of composite numbers.

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

3 + 5 + 13 + 17 + 19 + 23 = 80 3 x 5 x 13 x 17 x 19 x 23 = 1,448,655

Multiply prime numbers or prime factors to find their product.

Prime numbers are used to find the product of the prime factors of composite numbers.

The LCM of a set of prime numbers is their product.

You need at least two numbers to find a GCF. The product of prime factors is 3 x 7 x 7 = 147

The GCF of any set of prime numbers is 1.

No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.

The GCF of two prime numbers is 1. 4, 9 and 25 are relatively prime.

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

Find their GCF.

The same as with smaller numbers. Every composite number, no matter the size, can be expressed as the product of prime factors. Comparing prime factorizations will give you the GCF.

To find the GCF of two numbers, you first split them both into their prime factors. 45 = 3x3x5 60 = 2x2x3x5 The next step is to find the common prime factors. In this case, both numbers have one 3 as a factor, and both have one 5 as a factor. To get the greatest common factor, we find the product of these common prime factors: 5x3=15 Thus the greatest common factor of 45 and 60 is 15.
