Lets's calculate LCM of 21,533,702

3 21, 533, 702
13 7, 533, 234
7, 41, 18

∴ So the LCM of the given numbers is 3 x 13 x 7 x 41 x 18 = 201474

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/201474

Therefore, the GCF of Fractions 15/21,97/533,958/702 is 1/201474

Least Common Multiple of 21,533,702 with GCF Formula

Least Common Multiple of 21,533,702 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 21,533,702 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,533,702) = 1

common factors(in case of two or more numbers have common factors) = 39

GCF(21,533,702) x common factors =1 x 39 = 39

LCM(21,533,702) = ( 21 × 533 × 702 ) / 39

LCM(21,533,702) = 7857486 / 39

LCM(21,533,702) = 201474
