LCM of:

Least Common Multiple of 45/245,55/775,225/780

Given numbers are 45/245,55/775,225/780

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 45,55,225

Least Common Multiple of Numerators i.e. LCM of 45,55,225 is 2475.

GCF of Denominators means GCF of 245,775,780 as per the given fractions.

GCF of 245,775,780 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 45,55,225

LCM of Fractions 45/245,55/775,225/780 is 495

3 45, 55, 225
3 15, 55, 75
5 5, 55, 25
1, 11, 5

∴ So the LCM of the given numbers is 3 x 3 x 5 x 1 x 11 x 5 = 2475

Least Common Multiple of 45,55,225 with GCF Formula

Least Common Multiple of 45,55,225 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 45,55,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,55,225) = 5

common factors(in case of two or more numbers have common factors) = 45

GCF(45,55,225) x common factors =5 x 45 = 225

LCM(45,55,225) = ( 45 × 55 × 225 ) / 225

LCM(45,55,225) = 556875 / 225

LCM(45,55,225) = 2475


Lets's calculate GCF of 245,775,780

5 245, 775, 780
49, 155, 156

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2475/5

Therefore the LCM of Fractions 45/245,55/775,225/780 is 495
