Least Common Multiple of 621, 438

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

• Least Common Multiple of 621, 438 by common division method
• Least Common Multiple of 621, 438 with GCF Formula

∴ So the LCM of the given numbers is 3 x 207 x 146 = 90666

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 621,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(621,438) = 3

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

GCF(621,438) x common factors =3 x 1 = 3

LCM(621,438) = ( 621 × 438 ) / 3

LCM(621,438) = 271998 / 3

LCM(621,438) = 90666

∴ Least Common Multiple of 621,438 is 90666

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

• LCM of 166, 317
• LCM of 865, 181
• LCM of 911, 697
• LCM of 973, 290
• LCM of 628, 679
