Least Common Multiple of 42, 81, 63, 987

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

• Least Common Multiple of 42, 81, 63, 987 by common division method
• Least Common Multiple of 42, 81, 63, 987 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 7 x 2 x 9 x 1 x 47 = 53298

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 42,81,63,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,81,63,987) = 3

common factors(in case of two or more numbers have common factors) = 1323

GCF(42,81,63,987) x common factors =3 x 1323 = 3969

LCM(42,81,63,987) = ( 42 × 81 × 63 × 987 ) / 3969

LCM(42,81,63,987) = 211539762 / 3969

LCM(42,81,63,987) = 53298

∴ Least Common Multiple of 42,81,63,987 is 53298
