Least Common Multiple of 18/44,51/68,378/396

Given numbers are 18/44,51/68,378/396

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 18,51,378

Least Common Multiple of Numerators i.e. LCM of 18,51,378 is 6426.

GCF of Denominators means GCF of 44,68,396 as per the given fractions.

GCF of 44,68,396 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 18,51,378

LCM of Fractions 18/44,51/68,378/396 is 6426/4

2 18, 51, 378
3 9, 51, 189
3 3, 17, 63
1, 17, 21

∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 17 x 21 = 6426

Least Common Multiple of 18,51,378 with GCF Formula

Least Common Multiple of 18,51,378 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 18,51,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,51,378) = 3

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

GCF(18,51,378) x common factors =3 x 18 = 54

LCM(18,51,378) = ( 18 × 51 × 378 ) / 54

LCM(18,51,378) = 347004 / 54

LCM(18,51,378) = 6426


Lets's calculate GCF of 44,68,396

2 44, 68, 396
2 22, 34, 198
11, 17, 99

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6426/4

Therefore the LCM of Fractions 18/44,51/68,378/396 is 6426/4
