Least Common Multiple of 210, 310, 21

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

• Least Common Multiple of 210, 310, 21 by common division method
• Least Common Multiple of 210, 310, 21 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 31 x 1 = 6510

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 210,310,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(210,310,21) = 1

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

GCF(210,310,21) x common factors =1 x 210 = 210

LCM(210,310,21) = ( 210 × 310 × 21 ) / 210

LCM(210,310,21) = 1367100 / 210

LCM(210,310,21) = 6510

∴ Least Common Multiple of 210,310,21 is 6510

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

• LCM of 482, 722, 94
• LCM of 911, 235, 47
• LCM of 145, 857, 21
• LCM of 437, 792, 46
• LCM of 846, 456, 12
