Lets's calculate LCM of 65,436,640

2 65, 436, 640
2 65, 218, 320
5 65, 109, 160
13, 109, 32

∴ So the LCM of the given numbers is 2 x 2 x 5 x 13 x 109 x 32 = 906880

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/906880

Therefore, the GCF of Fractions 87/65,47/436,101/640 is 1/906880

Least Common Multiple of 65,436,640 with GCF Formula

Least Common Multiple of 65,436,640 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 65,436,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,436,640) = 1

common factors(in case of two or more numbers have common factors) = 20

GCF(65,436,640) x common factors =1 x 20 = 20

LCM(65,436,640) = ( 65 × 436 × 640 ) / 20

LCM(65,436,640) = 18137600 / 20

LCM(65,436,640) = 906880
