So the greatest common factor 989,651,618 is 1.

Lets's calculate LCM of 12,36,43

2 12, 36, 43
2 6, 18, 43
3 3, 9, 43
1, 3, 43

∴ So the LCM of the given numbers is 2 x 2 x 3 x 1 x 3 x 43 = 1548

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1548

Therefore, the GCF of Fractions 989/12,651/36,618/43 is 1/1548

Least Common Multiple of 12,36,43 with GCF Formula

Least Common Multiple of 12,36,43 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 12,36,43 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,36,43) = 1

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

GCF(12,36,43) x common factors =1 x 12 = 12

LCM(12,36,43) = ( 12 × 36 × 43 ) / 12

LCM(12,36,43) = 18576 / 12

LCM(12,36,43) = 1548
