Least Common Multiple of 70, 81, 810

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

• Least Common Multiple of 70, 81, 810 by common division method
• Least Common Multiple of 70, 81, 810 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 5 x 7 x 1 x 1 = 5670

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 70,81,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,81,810) = 1

common factors(in case of two or more numbers have common factors) = 810

GCF(70,81,810) x common factors =1 x 810 = 810

LCM(70,81,810) = ( 70 × 81 × 810 ) / 810

LCM(70,81,810) = 4592700 / 810

LCM(70,81,810) = 5670

∴ Least Common Multiple of 70,81,810 is 5670

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

• LCM of 15, 95, 759
• LCM of 82, 22, 523
• LCM of 14, 73, 536
• LCM of 24, 32, 243
• LCM of 85, 11, 909
