Greatest Common Factor

We found the factors 51,64,31,51 . The biggest common factor number is the GCF number.
So the greatest common factor 51,64,31,51 is 1.

Lets's calculate LCM of 57,42,73,320

2 57, 42, 73, 320
3 57, 21, 73, 160
19, 7, 73, 160

∴ So the LCM of the given numbers is 2 x 3 x 19 x 7 x 73 x 160 = 9320640

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9320640

Therefore, the GCF of Fractions 51/57,64/42,31/73,51/320 is 1/9320640

Least Common Multiple of 57,42,73,320 with GCF Formula

Least Common Multiple of 57,42,73,320 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 57,42,73,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,42,73,320) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(57,42,73,320) x common factors =1 x 6 = 6

LCM(57,42,73,320) = ( 57 × 42 × 73 × 320 ) / 6

LCM(57,42,73,320) = 55923840 / 6

LCM(57,42,73,320) = 9320640
