Least Common Multiple of 210, 425, 21

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

• Least Common Multiple of 210, 425, 21 by common division method
• Least Common Multiple of 210, 425, 21 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 7 x 2 x 85 x 1 = 17850

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 210,425,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(210,425,21) = 1

common factors(in case of two or more numbers have common factors) = 105

GCF(210,425,21) x common factors =1 x 105 = 105

LCM(210,425,21) = ( 210 × 425 × 21 ) / 105

LCM(210,425,21) = 1874250 / 105

LCM(210,425,21) = 17850

∴ Least Common Multiple of 210,425,21 is 17850

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

• LCM of 335, 442, 77
• LCM of 628, 629, 63
• LCM of 501, 677, 19
