So the greatest common factor 16,90,68,39 is 1.

Lets's calculate LCM of 63,71,21,64

3 63, 71, 21, 64
7 21, 71, 7, 64
3, 71, 1, 64

∴ So the LCM of the given numbers is 3 x 7 x 3 x 71 x 1 x 64 = 286272

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/286272

Therefore, the GCF of Fractions 16/63,90/71,68/21,39/64 is 1/286272

Least Common Multiple of 63,71,21,64 with GCF Formula

Least Common Multiple of 63,71,21,64 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 63,71,21,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,71,21,64) = 1

common factors(in case of two or more numbers have common factors) = 21

GCF(63,71,21,64) x common factors =1 x 21 = 21

LCM(63,71,21,64) = ( 63 × 71 × 21 × 64 ) / 21

LCM(63,71,21,64) = 6011712 / 21

LCM(63,71,21,64) = 286272
