Greatest Common Factor

We found the factors 98,69,90,20 . The biggest common factor number is the GCF number.
So the greatest common factor 98,69,90,20 is 1.

Lets's calculate LCM of 11,47,22,99

11 11, 47, 22, 99
1, 47, 2, 9

∴ So the LCM of the given numbers is 11 x 1 x 47 x 2 x 9 = 9306

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9306

Therefore, the GCF of Fractions 98/11,69/47,90/22,20/99 is 1/9306

Least Common Multiple of 11,47,22,99 with GCF Formula

Least Common Multiple of 11,47,22,99 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 11,47,22,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(11,47,22,99) = 1

common factors(in case of two or more numbers have common factors) = 121

GCF(11,47,22,99) x common factors =1 x 121 = 121

LCM(11,47,22,99) = ( 11 × 47 × 22 × 99 ) / 121

LCM(11,47,22,99) = 1126026 / 121

LCM(11,47,22,99) = 9306
