Least Common Multiple of 1981, 1431

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

• Least Common Multiple of 1981, 1431 by common division method
• Least Common Multiple of 1981, 1431 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 2834811

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 1981,1431 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1981,1431) = 1

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

GCF(1981,1431) x common factors =1 x 1 = 1

LCM(1981,1431) = ( 1981 × 1431 ) / 1

LCM(1981,1431) = 2834811 / 1

LCM(1981,1431) = 2834811

∴ Least Common Multiple of 1981,1431 is 2834811

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

• LCM of 1042, 4841
• LCM of 1057, 4338
• LCM of 9381, 3599
• LCM of 6744, 2130
