Least Common Multiple of 636, 138, 15

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

• Least Common Multiple of 636, 138, 15 by common division method
• Least Common Multiple of 636, 138, 15 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 106 x 23 x 5 = 73140

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 636,138,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(636,138,15) = 3

common factors(in case of two or more numbers have common factors) = 6

GCF(636,138,15) x common factors =3 x 6 = 18

LCM(636,138,15) = ( 636 × 138 × 15 ) / 18

LCM(636,138,15) = 1316520 / 18

LCM(636,138,15) = 73140

∴ Least Common Multiple of 636,138,15 is 73140

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

• LCM of 320, 440, 11
• LCM of 277, 191, 74
• LCM of 814, 915, 85
• LCM of 651, 888, 73
• LCM of 521, 409, 70
