Lets's calculate LCM of 10,36,54

2 10, 36, 54
3 5, 18, 27
3 5, 6, 9
5, 2, 3

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 2 x 3 = 540

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/540

Least Common Multiple of 10,36,54 with GCF Formula

Least Common Multiple of 10,36,54 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 10,36,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,36,54) = 2

common factors(in case of two or more numbers have common factors) = 18

GCF(10,36,54) x common factors =2 x 18 = 36

LCM(10,36,54) = ( 10 × 36 × 54 ) / 36

LCM(10,36,54) = 19440 / 36

LCM(10,36,54) = 540
