LCM of:

Least Common Multiple of 42/357,42/728,469/217

Given numbers are 42/357,42/728,469/217

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 42,42,469

Least Common Multiple of Numerators i.e. LCM of 42,42,469 is 2814.

GCF of Denominators means GCF of 357,728,217 as per the given fractions.

GCF of 357,728,217 is 7 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,42,469

LCM of Fractions 42/357,42/728,469/217 is 402

2 42, 42, 469
3 21, 21, 469
7 7, 7, 469
1, 1, 67

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 1 x 67 = 2814

Least Common Multiple of 42,42,469 with GCF Formula

Least Common Multiple of 42,42,469 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 42,42,469 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,42,469) = 7

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

GCF(42,42,469) x common factors =7 x 42 = 294

LCM(42,42,469) = ( 42 × 42 × 469 ) / 294

LCM(42,42,469) = 827316 / 294

LCM(42,42,469) = 2814


Lets's calculate GCF of 357,728,217

7 357, 728, 217
51, 104, 31

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2814/7

Therefore the LCM of Fractions 42/357,42/728,469/217 is 402
