Lets's calculate LCM of 69,92,42

2 69, 92, 42
3 69, 46, 21
23 23, 46, 7
1, 2, 7

∴ So the LCM of the given numbers is 2 x 3 x 23 x 1 x 2 x 7 = 1932

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/1932

Therefore, the GCF of Fractions 49/69,63/92,14/42 is 7/1932

Least Common Multiple of 69,92,42 with GCF Formula

Least Common Multiple of 69,92,42 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 69,92,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,92,42) = 1

common factors(in case of two or more numbers have common factors) = 138

GCF(69,92,42) x common factors =1 x 138 = 138

LCM(69,92,42) = ( 69 × 92 × 42 ) / 138

LCM(69,92,42) = 266616 / 138

LCM(69,92,42) = 1932
