Least Common Multiple of 490, 420, 78

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

• Least Common Multiple of 490, 420, 78 by common division method
• Least Common Multiple of 490, 420, 78 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 7 x 2 x 13 = 38220

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 490,420,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(490,420,78) = 2

common factors(in case of two or more numbers have common factors) = 210

GCF(490,420,78) x common factors =2 x 210 = 420

LCM(490,420,78) = ( 490 × 420 × 78 ) / 420

LCM(490,420,78) = 16052400 / 420

LCM(490,420,78) = 38220

∴ Least Common Multiple of 490,420,78 is 38220

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

• LCM of 654, 746, 89
• LCM of 120, 200, 69
