Least Common Multiple of 987, 1689

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

• Least Common Multiple of 987, 1689 by common division method
• Least Common Multiple of 987, 1689 with GCF Formula

∴ So the LCM of the given numbers is 3 x 329 x 563 = 555681

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 987,1689 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(987,1689) = 3

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

GCF(987,1689) x common factors =3 x 1 = 3

LCM(987,1689) = ( 987 × 1689 ) / 3

LCM(987,1689) = 1667043 / 3

LCM(987,1689) = 555681

∴ Least Common Multiple of 987,1689 is 555681

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

• LCM of 561, 7879
• LCM of 189, 5210
• LCM of 452, 6807
• LCM of 202, 1323
• LCM of 816, 1340
