Least Common Multiple of 420, 1790

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

• Least Common Multiple of 420, 1790 by common division method
• Least Common Multiple of 420, 1790 with GCF Formula

∴ So the LCM of the given numbers is 2 x 5 x 42 x 179 = 75180

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 420,1790 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,1790) = 10

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

GCF(420,1790) x common factors =10 x 1 = 10

LCM(420,1790) = ( 420 × 1790 ) / 10

LCM(420,1790) = 751800 / 10

LCM(420,1790) = 75180

∴ Least Common Multiple of 420,1790 is 75180

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

• LCM of 646, 8673
• LCM of 989, 4668
• LCM of 129, 1925
• LCM of 552, 2413
