Lets's calculate LCM of 12,40,83

2 12, 40, 83
2 6, 20, 83
3, 10, 83

∴ So the LCM of the given numbers is 2 x 2 x 3 x 10 x 83 = 9960

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9960

Therefore, the GCF of Fractions 641/12,254/40,248/83 is 1/9960

Least Common Multiple of 12,40,83 with GCF Formula

Least Common Multiple of 12,40,83 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 12,40,83 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,40,83) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(12,40,83) x common factors =1 x 4 = 4

LCM(12,40,83) = ( 12 × 40 × 83 ) / 4

LCM(12,40,83) = 39840 / 4

LCM(12,40,83) = 9960
