Best Answer

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.

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.

6=2*3 7=7 8=2*2*2 6 and 8 both have 2's, but 8 has more. Cross out the 2 from 6. 3*7*2*2*2 =168

{ [(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

The Greatest Common Factor (GCF) is: 1 .The greatest common multiple of any set of integers is infinite.

The greatest common multiple of any set of integers is infinite.

The GCM would be 9 because if you multiply 9*4=36 9*5=45 9*7=63(:

The greatest common multiple of any set of integers is infinite.

There is not a unique answer. (3,36) and (9,12) are two possible solutions.

You need at least two numbers to find an LCM. The GCM of any two integers is infinite.

Density = Mass/Volume = 112/24 gcm-3 = 4.667 gcm-3

The greatest common multiple of any set of integers is infinite.

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

0.791 gcm-3. :)
