Least Common Multiple of 70, 21, 945

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

• Least Common Multiple of 70, 21, 945 by common division method
• Least Common Multiple of 70, 21, 945 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 7 x 2 x 1 x 9 = 1890

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 70,21,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,21,945) = 7

common factors(in case of two or more numbers have common factors) = 105

GCF(70,21,945) x common factors =7 x 105 = 735

LCM(70,21,945) = ( 70 × 21 × 945 ) / 735

LCM(70,21,945) = 1389150 / 735

LCM(70,21,945) = 1890

∴ Least Common Multiple of 70,21,945 is 1890

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 27, 16, 918
• LCM of 81, 34, 644
