So the greatest common factor 90,150,225 is 15.


Lets's calculate LCM of 45,75,225

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

∴ So the LCM of the given numbers is 3 x 3 x 5 x 5 x 1 x 1 x 1 = 225

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/225

Least Common Multiple of 45,75,225 with GCF Formula

Least Common Multiple of 45,75,225 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 45,75,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,75,225) = 15

common factors(in case of two or more numbers have common factors) = 225

GCF(45,75,225) x common factors =15 x 225 = 3375

LCM(45,75,225) = ( 45 × 75 × 225 ) / 3375

LCM(45,75,225) = 759375 / 3375

LCM(45,75,225) = 225
