Least Common Multiple of 974, 974, 21

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

• Least Common Multiple of 974, 974, 21 by common division method
• Least Common Multiple of 974, 974, 21 with GCF Formula

∴ So the LCM of the given numbers is 2 x 487 x 1 x 1 x 21 = 20454

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 974,974,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(974,974,21) = 1

common factors(in case of two or more numbers have common factors) = 974

GCF(974,974,21) x common factors =1 x 974 = 974

LCM(974,974,21) = ( 974 × 974 × 21 ) / 974

LCM(974,974,21) = 19922196 / 974

LCM(974,974,21) = 20454

∴ Least Common Multiple of 974,974,21 is 20454

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

• LCM of 695, 209, 48
• LCM of 344, 580, 79
• LCM of 551, 550, 31
