Least Common Multiple of 70, 21, 735

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

• Least Common Multiple of 70, 21, 735 by common division method
• Least Common Multiple of 70, 21, 735 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 7 x 2 x 1 x 7 = 1470

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 70,21,735 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,21,735) = 7

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

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

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

LCM(70,21,735) = 1080450 / 735

LCM(70,21,735) = 1470

∴ Least Common Multiple of 70,21,735 is 1470

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

• LCM of 38, 54, 508
• LCM of 28, 88, 707
• LCM of 36, 31, 685
