Least Common Multiple of 1780, 1123

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

• Least Common Multiple of 1780, 1123 by common division method
• Least Common Multiple of 1780, 1123 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1998940

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 1780,1123 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1780,1123) = 1

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

GCF(1780,1123) x common factors =1 x 1 = 1

LCM(1780,1123) = ( 1780 × 1123 ) / 1

LCM(1780,1123) = 1998940 / 1

LCM(1780,1123) = 1998940

∴ Least Common Multiple of 1780,1123 is 1998940

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

• LCM of 4368, 1453
• LCM of 5589, 3458
• LCM of 3901, 3767
• LCM of 9789, 2232
