Greatest Common Factor

We found the factors 68,31,990 . The biggest common factor number is the GCF number.
So the greatest common factor 68,31,990 is 1.

Lets's calculate LCM of 12,55,102

2 12, 55, 102
3 6, 55, 51
2, 55, 17

∴ So the LCM of the given numbers is 2 x 3 x 2 x 55 x 17 = 11220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11220

Therefore, the GCF of Fractions 68/12,31/55,990/102 is 1/11220

Least Common Multiple of 12,55,102 with GCF Formula

Least Common Multiple of 12,55,102 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 12,55,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,55,102) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(12,55,102) x common factors =1 x 6 = 6

LCM(12,55,102) = ( 12 × 55 × 102 ) / 6

LCM(12,55,102) = 67320 / 6

LCM(12,55,102) = 11220
