Lets's calculate LCM of 69,40,676

2 69, 40, 676
2 69, 20, 338
69, 10, 169

∴ So the LCM of the given numbers is 2 x 2 x 69 x 10 x 169 = 466440

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/466440

Therefore, the GCF of Fractions 54/69,19/40,457/676 is 1/466440

Least Common Multiple of 69,40,676 with GCF Formula

Least Common Multiple of 69,40,676 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 69,40,676 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,40,676) = 1

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

GCF(69,40,676) x common factors =1 x 4 = 4

LCM(69,40,676) = ( 69 × 40 × 676 ) / 4

LCM(69,40,676) = 1865760 / 4

LCM(69,40,676) = 466440
