LCM of 13/22, 65/38, 99/990

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 13/22,65/38,99/990

Given numbers are 13/22,65/38,99/990

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 13,65,99

Least Common Multiple of Numerators i.e. LCM of 13,65,99 is 6435.

GCF of Denominators means GCF of 22,38,990 as per the given fractions.

GCF of 22,38,990 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,65,99

LCM of Fractions 13/22,65/38,99/990 is 6435/2

13 13, 65, 99
1, 5, 99

∴ So the LCM of the given numbers is 13 x 1 x 5 x 99 = 6435

Least Common Multiple of 13,65,99 with GCF Formula

Least Common Multiple of 13,65,99 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 13,65,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,65,99) = 1

common factors(in case of two or more numbers have common factors) = 13

GCF(13,65,99) x common factors =1 x 13 = 13

LCM(13,65,99) = ( 13 × 65 × 99 ) / 13

LCM(13,65,99) = 83655 / 13

LCM(13,65,99) = 6435


Lets's calculate GCF of 22,38,990

2 22, 38, 990
11, 19, 495

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6435/2

Therefore the LCM of Fractions 13/22,65/38,99/990 is 6435/2
