So the greatest common factor 130,143,515 is 1.

Lets's calculate LCM of 42,56,668

2 42, 56, 668
2 21, 28, 334
7 21, 14, 167
3, 2, 167

∴ So the LCM of the given numbers is 2 x 2 x 7 x 3 x 2 x 167 = 28056

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28056

Therefore, the GCF of Fractions 130/42,143/56,515/668 is 1/28056

Least Common Multiple of 42,56,668 with GCF Formula

Least Common Multiple of 42,56,668 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 42,56,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,56,668) = 2

common factors(in case of two or more numbers have common factors) = 28

GCF(42,56,668) x common factors =2 x 28 = 56

LCM(42,56,668) = ( 42 × 56 × 668 ) / 56

LCM(42,56,668) = 1571136 / 56

LCM(42,56,668) = 28056
