Lets's calculate LCM of 12,43,492

2 12, 43, 492
2 6, 43, 246
3 3, 43, 123
1, 43, 41

∴ So the LCM of the given numbers is 2 x 2 x 3 x 1 x 43 x 41 = 21156

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21156

Therefore, the GCF of Fractions 87/12,73/43,111/492 is 1/21156

Least Common Multiple of 12,43,492 with GCF Formula

Least Common Multiple of 12,43,492 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 12,43,492 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,43,492) = 1

common factors(in case of two or more numbers have common factors) = 12

GCF(12,43,492) x common factors =1 x 12 = 12

LCM(12,43,492) = ( 12 × 43 × 492 ) / 12

LCM(12,43,492) = 253872 / 12

LCM(12,43,492) = 21156
