Least Common Multiple of 28, 140, 490

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

• Least Common Multiple of 28, 140, 490 by common division method
• Least Common Multiple of 28, 140, 490 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 1 x 7 = 980

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 28,140,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,140,490) = 14

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

GCF(28,140,490) x common factors =14 x 140 = 1960

LCM(28,140,490) = ( 28 × 140 × 490 ) / 1960

LCM(28,140,490) = 1920800 / 1960

LCM(28,140,490) = 980

∴ Least Common Multiple of 28,140,490 is 980

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

• LCM of 93, 791, 912
• LCM of 23, 352, 971
• LCM of 74, 575, 405
