Least Common Multiple of 420, 3821

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

• Least Common Multiple of 420, 3821 by common division method
• Least Common Multiple of 420, 3821 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1604820

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 420,3821 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,3821) = 1

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

GCF(420,3821) x common factors =1 x 1 = 1

LCM(420,3821) = ( 420 × 3821 ) / 1

LCM(420,3821) = 1604820 / 1

LCM(420,3821) = 1604820

∴ Least Common Multiple of 420,3821 is 1604820

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

• LCM of 826, 7363
• LCM of 371, 4687
• LCM of 207, 5247
• LCM of 716, 7686
• LCM of 816, 1292
