Lets's calculate LCM of 6,21,28

Least Common Multiple (LCM) of 6,21,28 By Common Division

2 6, 21, 28
3 3, 21, 14
7 1, 7, 14
1, 1, 2

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 1 x 2 = 84

Least Common Multiple of 6,21,28 with GCF Formula

Least Common Multiple of 6,21,28 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 6,21,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(6,21,28) = 1

common factors(in case of two or more numbers have common factors) = 42

GCF(6,21,28) x common factors =1 x 42 = 42

LCM(6,21,28) = ( 6 × 21 × 28 ) / 42

LCM(6,21,28) = 3528 / 42

LCM(6,21,28) = 84


Lets's calculate GCF of 378,485,500

Greatest Common Factor (GCF) of 378,485,500 By Common Division

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 84/1

Therefore the LCM of Fractions 6/378,21/485,28/500 is 84
