Greatest Common Factor

We found the factors 38,24,820 . The biggest common factor number is the GCF number.
So the greatest common factor 38,24,820 is 2.

Lets's calculate LCM of 11,72,512

2 11, 72, 512
2 11, 36, 256
2 11, 18, 128
11, 9, 64

∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 9 x 64 = 50688

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/50688

Therefore, the GCF of Fractions 38/11,24/72,820/512 is 2/50688

Least Common Multiple of 11,72,512 with GCF Formula

Least Common Multiple of 11,72,512 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 11,72,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(11,72,512) = 1

common factors(in case of two or more numbers have common factors) = 8

GCF(11,72,512) x common factors =1 x 8 = 8

LCM(11,72,512) = ( 11 × 72 × 512 ) / 8

LCM(11,72,512) = 405504 / 8

LCM(11,72,512) = 50688
