Least Common Multiple of 1689, 1649

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

• Least Common Multiple of 1689, 1649 by common division method
• Least Common Multiple of 1689, 1649 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 2785161

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 1689,1649 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1689,1649) = 1

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

GCF(1689,1649) x common factors =1 x 1 = 1

LCM(1689,1649) = ( 1689 × 1649 ) / 1

LCM(1689,1649) = 2785161 / 1

LCM(1689,1649) = 2785161

∴ Least Common Multiple of 1689,1649 is 2785161

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

• LCM of 6466, 4335
• LCM of 4611, 3698
• LCM of 6882, 3196
• LCM of 2276, 3200
