LCM(90, 105, 945) = 1890

LCM of 90, 105, 945

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 90,105,945

Least Common Multiple (LCM) of 90,105,945 is 1890

3 90, 105, 945
3 30, 35, 315
5 10, 35, 105
7 2, 7, 21
2, 1, 3

∴ So the LCM of the given numbers is 3 x 3 x 5 x 7 x 2 x 1 x 3 = 1890

Least Common Multiple of 90,105,945 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 90,105,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,105,945) = 15

common factors(in case of two or more numbers have common factors) = 315

GCF(90,105,945) x common factors =15 x 315 = 4725

LCM(90,105,945) = ( 90 × 105 × 945 ) / 4725

LCM(90,105,945) = 8930250 / 4725

LCM(90,105,945) = 1890

∴ Least Common Multiple of 90,105,945 is 1890
