Greatest Common Factor

We found the factors 644,425,852 . The biggest common factor number is the GCF number.
So the greatest common factor 644,425,852 is 1.

Lets's calculate LCM of 64,60,90

2 64, 60, 90
2 32, 30, 45
3 16, 15, 45
5 16, 5, 15
16, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 16 x 1 x 3 = 2880

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2880

Therefore, the GCF of Fractions 644/64,425/60,852/90 is 1/2880

Least Common Multiple of 64,60,90 with GCF Formula

Least Common Multiple of 64,60,90 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 64,60,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(64,60,90) = 2

common factors(in case of two or more numbers have common factors) = 60

GCF(64,60,90) x common factors =2 x 60 = 120

LCM(64,60,90) = ( 64 × 60 × 90 ) / 120

LCM(64,60,90) = 345600 / 120

LCM(64,60,90) = 2880
