Lets's calculate LCM of 22,77,990

2 22, 77, 990
11 11, 77, 495
1, 7, 45

∴ So the LCM of the given numbers is 2 x 11 x 1 x 7 x 45 = 6930

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6930

Therefore, the GCF of Fractions 447/22,642/77,243/990 is 3/6930

Least Common Multiple of 22,77,990 with GCF Formula

Least Common Multiple of 22,77,990 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 22,77,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(22,77,990) = 11

common factors(in case of two or more numbers have common factors) = 22

GCF(22,77,990) x common factors =11 x 22 = 242

LCM(22,77,990) = ( 22 × 77 × 990 ) / 242

LCM(22,77,990) = 1677060 / 242

LCM(22,77,990) = 6930
