Least Common Multiple of 12, 80, 400

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

• Least Common Multiple of 12, 80, 400 by common division method
• Least Common Multiple of 12, 80, 400 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 3 x 1 x 5 = 1200

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 12,80,400 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,80,400) = 4

common factors(in case of two or more numbers have common factors) = 80

GCF(12,80,400) x common factors =4 x 80 = 320

LCM(12,80,400) = ( 12 × 80 × 400 ) / 320

LCM(12,80,400) = 384000 / 320

LCM(12,80,400) = 1200

∴ Least Common Multiple of 12,80,400 is 1200

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

• LCM of 97, 78, 687
• LCM of 48, 81, 445
• LCM of 26, 31, 266
• LCM of 54, 55, 785
