Least Common Multiple of 721, 1389

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

• Least Common Multiple of 721, 1389 by common division method
• Least Common Multiple of 721, 1389 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1001469

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 721,1389 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(721,1389) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(721,1389) x common factors =1 x 1 = 1

LCM(721,1389) = ( 721 × 1389 ) / 1

LCM(721,1389) = 1001469 / 1

LCM(721,1389) = 1001469

∴ Least Common Multiple of 721,1389 is 1001469

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

• LCM of 261, 1822
• LCM of 154, 6590
• LCM of 532, 5102
• LCM of 230, 3883
• LCM of 550, 7863
