Lets's calculate LCM of 13,378,126

2 13, 378, 126
3 13, 189, 63
3 13, 21, 63
7 13, 7, 21
13, 1, 3

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 13 x 1 x 3 = 4914

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4914

Therefore, the GCF of Fractions 4/13,49/378,40/126 is 1/4914

Least Common Multiple of 13,378,126 with GCF Formula

Least Common Multiple of 13,378,126 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 13,378,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,378,126) = 1

common factors(in case of two or more numbers have common factors) = 126

GCF(13,378,126) x common factors =1 x 126 = 126

LCM(13,378,126) = ( 13 × 378 × 126 ) / 126

LCM(13,378,126) = 619164 / 126

LCM(13,378,126) = 4914
