Least Common Multiple of 1409, 1221

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

• Least Common Multiple of 1409, 1221 by common division method
• Least Common Multiple of 1409, 1221 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1720389

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 1409,1221 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1409,1221) = 1

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

GCF(1409,1221) x common factors =1 x 1 = 1

LCM(1409,1221) = ( 1409 × 1221 ) / 1

LCM(1409,1221) = 1720389 / 1

LCM(1409,1221) = 1720389

∴ Least Common Multiple of 1409,1221 is 1720389

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

• LCM of 2155, 8681
• LCM of 7689, 1858
• LCM of 2057, 1656
• LCM of 8672, 7275
• LCM of 5616, 4491
