Least Common Multiple of 980, 700, 20

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

• Least Common Multiple of 980, 700, 20 by common division method
• Least Common Multiple of 980, 700, 20 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 7 x 5 x 1 = 4900

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 980,700,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(980,700,20) = 20

common factors(in case of two or more numbers have common factors) = 140

GCF(980,700,20) x common factors =20 x 140 = 2800

LCM(980,700,20) = ( 980 × 700 × 20 ) / 2800

LCM(980,700,20) = 13720000 / 2800

LCM(980,700,20) = 4900

∴ Least Common Multiple of 980,700,20 is 4900

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

• LCM of 748, 481, 56
• LCM of 163, 731, 58
• LCM of 634, 545, 88
• LCM of 449, 294, 88
