Least Common Multiple of 1220, 1604

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

• Least Common Multiple of 1220, 1604 by common division method
• Least Common Multiple of 1220, 1604 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 305 x 401 = 489220

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 1220,1604 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1220,1604) = 4

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

GCF(1220,1604) x common factors =4 x 1 = 4

LCM(1220,1604) = ( 1220 × 1604 ) / 4

LCM(1220,1604) = 1956880 / 4

LCM(1220,1604) = 489220

∴ Least Common Multiple of 1220,1604 is 489220

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

• LCM of 1810, 5273
• LCM of 6286, 5079
• LCM of 1222, 8978
• LCM of 1067, 7692
