Greatest Common Factor

We found the factors 28,64,49,30 . The biggest common factor number is the GCF number.
So the greatest common factor 28,64,49,30 is 1.

Lets's calculate LCM of 22,55,13,626

2 22, 55, 13, 626
11 11, 55, 13, 313
1, 5, 13, 313

∴ So the LCM of the given numbers is 2 x 11 x 1 x 5 x 13 x 313 = 447590

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/447590

Therefore, the GCF of Fractions 28/22,64/55,49/13,30/626 is 1/447590

Least Common Multiple of 22,55,13,626 with GCF Formula

Least Common Multiple of 22,55,13,626 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 22,55,13,626 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(22,55,13,626) = 1

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

GCF(22,55,13,626) x common factors =1 x 22 = 22

LCM(22,55,13,626) = ( 22 × 55 × 13 × 626 ) / 22

LCM(22,55,13,626) = 9846980 / 22

LCM(22,55,13,626) = 447590
