Lets's calculate LCM of 93,51,72,21

3 93, 51, 72, 21
31, 17, 24, 7

∴ So the LCM of the given numbers is 3 x 31 x 17 x 24 x 7 = 265608

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/265608

Therefore, the GCF of Fractions 1/93,82/51,47/72,20/21 is 1/265608

Least Common Multiple of 93,51,72,21 with GCF Formula

Least Common Multiple of 93,51,72,21 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 93,51,72,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(93,51,72,21) = 3

common factors(in case of two or more numbers have common factors) = 9

GCF(93,51,72,21) x common factors =3 x 9 = 27

LCM(93,51,72,21) = ( 93 × 51 × 72 × 21 ) / 27

LCM(93,51,72,21) = 7171416 / 27

LCM(93,51,72,21) = 265608
