Least Common Multiple of 1281, 1681

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

• Least Common Multiple of 1281, 1681 by common division method
• Least Common Multiple of 1281, 1681 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 2153361

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 1281,1681 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1281,1681) = 1

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

GCF(1281,1681) x common factors =1 x 1 = 1

LCM(1281,1681) = ( 1281 × 1681 ) / 1

LCM(1281,1681) = 2153361 / 1

LCM(1281,1681) = 2153361

∴ Least Common Multiple of 1281,1681 is 2153361

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

• LCM of 6574, 8733
• LCM of 4935, 9221
• LCM of 9235, 7387
• LCM of 3488, 6845
