Best Answer

It must be less than or equal to the smallest of the set of numbers whose GCF you are trying to obtain. So it must be less than or equal to 16.

Furthermore, it is not 16 because 16 is not a factor of 42. Therefore, it must be less than 16.

It can and it is. 16 is not a factor of 42. 16 can't have a factor greater than itself, so the GCF must be lesser.

The GCF is 16.

You don't. There's no question there, and nothing that needs solving. "16 less than x squared" is written as (x2 - 16)

p is less than 12.

The equation 7x-12 is less than 4x plus 36 means just what it says7x - 12 less than 4x + 36To solve this, treat it like ordinary algebra and solve for x, replacing the equals sign with the less than sign. Remember that if you multiply or divide by a negative number, then the less than sign flips over and becomes the greater than sign.7x - 12 less than 4x + 367x less than 4x + 487x - 4x less than 483x less than 48x less than 16

There is no GCF of 16. You need at least two numbers to find a GCF. The GCF of something and 16 could possibly be less than 16.

Since 16 is not a factor of 42, the GCF in this case has to be less than 16.

yes... 16 is not a factor of 42 GCF is 2

Since 16 is not a factor of 40, the GCF must be less than 16.

The only rule is that the GCF has to be equal to or less than the lower number. Since 16 is not the GCF of 16 and 42, the GCF has to be lower than 16.

It can be and is. Since 16 is not a factor of 42, the GCF will have to be a factor of 16 that is less than 16.

It can be and is.

Yes, it's 8

Yes. The greatest common factor of 16 and 42 must be a factor of 16. The only rule is that the GCF has to be equal to or less than the lower number. Since 16 is not the GCF of 16 and 42, the GCF has to be lower than 16.

Yes.

because 16 is not a factor of 42 and the GCF is 2.
