Product means "multiply"
So 7 x 9 x 2 = 126
7+9=16 7x9=63 63-16 = 47
182.
The GCF is 1.
126
It is: 126
2, 7, and 17 are all prime numbers, so their LCM is their product: 2 x 7 x 17 = 238
63
9 is not prime
It is one
The product of two numbers is the number that results when they are multiplied by each other. So the product of 2 and 9 = 2 * 9, or 18.
71/2
