The GCF is 7. The LCM is 14.

The LCM of 3, 5 and 7 is 105. The GCF is 1.

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.

Of 7, 77 and 770:gcf is 7;lcm is 770.

The LCM of 7 and 15 is 105. The GCF of 7 and 15 is 1.

Gcf=3, lcm=9

They are gcf = 3 and LCM = 6

GCF is 7 LCM is 588

LCM is 105. GCF is 1.

The LCM is: 441The GCF is: 7

LCM = 70 GCF = 7

Gcf=7 lcm=98

Lcm: 126 gcf: 7

35 and 7, respectively.

To make this easier, let's first factor 18 and 21 into their prime factors: 18=2*3^2 21=3*7 Now it's very easy to find the LCM and GCF. The LCM is 2*3^2*7=126, and the GCF is 3.

The GCF is 210.. I believe..so nevermind.

The GCF is 3. The LCM is 45.

GCF is 7. LCM is 420

gcf: 7 lcm: 588

GCF: 7 LCM: 210

3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630

I think that should be the other way around. 7 and 56 have a GCF of 7 and an LCM of 56.

84 and 1, respectively.

Gcf= 3 lcm=78

The GCF is 3. The LCM is 99.
