It's either GCF (Greatest Common Factor) or LCM (Least Common Multiple).

GCF of 3 and 9 is 3, but seven only has 1 as a common factor with the other two, so GCF is 1.

LCM of 3 & 9 is 9, and LCM of 9 and 7 is 7 x 9, so LCM is 63.

The gcm for 9 and 12 would be 3. :)


What is the GCM of 7 and 13?

There can be no GCM (Greatest Common Multiple). Suppose a GCM exists and suppose it is x. That is, x is the GCM of 7 and 13, then 2x is a multiple of both 7 and 13 and is greater than x. This contradicts the statement that x is the GCM. So x cannot be the GCM.

Why is 1 the gcm for 7 9 0?

Because any two of the three numbers are coprime. That is, they do not have any factor, other than 1, in common.


How does 1 3 5 7 9 equal 3?

{ [(1+3) *5 ] +7 } /9 = 3 [4 *5] + 7 = 27 divided by 9 = 3 also [ (1+3) / (5+7) ] * 9 = 3 More complex is 13 * (5+7) - 9 = 3 with just signs : -1 -3 +5 -7 + 9 = 3
