LCM(345/2, 42/15) = 4830

LCM of 345/2, 42/15

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 345/2,42/15

Given numbers are 345/2,42/15

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 345,42

Least Common Multiple of Numerators i.e. LCM of 345,42 is 4830.

GCF of Denominators means GCF of 2,15 as per the given fractions.

GCF of 2,15 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 345,42

LCM of Fractions 345/2,42/15 is 4830

3 345, 42
115, 14

∴ So the LCM of the given numbers is 3 x 115 x 14 = 4830

Least Common Multiple of 345,42 with GCF Formula

Least Common Multiple of 345,42 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 345,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(345,42) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(345,42) x common factors =3 x 1 = 3

LCM(345,42) = ( 345 × 42 ) / 3

LCM(345,42) = 14490 / 3

LCM(345,42) = 4830


Lets's calculate GCF of 2,15

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4830/1

Therefore the LCM of Fractions 345/2,42/15 is 4830
