Lets's calculate LCM of 70,98,147

Least Common Multiple (LCM) of 70,98,147 By Common Division

2 70, 98, 147
7 35, 49, 147
7 5, 7, 21
5, 1, 3

∴ So the LCM of the given numbers is 2 x 7 x 7 x 5 x 1 x 3 = 1470

Least Common Multiple of 70,98,147 with GCF Formula

Least Common Multiple of 70,98,147 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 70,98,147 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,98,147) = 7

common factors(in case of two or more numbers have common factors) = 14

GCF(70,98,147) x common factors =7 x 14 = 98

LCM(70,98,147) = ( 70 × 98 × 147 ) / 98

LCM(70,98,147) = 1008420 / 98

LCM(70,98,147) = 1470


Lets's calculate GCF of 108,120,144

Greatest Common Factor (GCF) of 108,120,144 By Common Division

2 108, 120, 144
2 54, 60, 72
3 27, 30, 36
9, 10, 12

∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1470/12

Therefore the LCM of Fractions 70/108,98/120,147/144 is 1470/12
