Least Common Multiple of 21, 5445

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

• Least Common Multiple of 21, 5445 by common division method
• Least Common Multiple of 21, 5445 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 1815 = 38115

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 21,5445 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,5445) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(21,5445) x common factors =3 x 1 = 3

LCM(21,5445) = ( 21 × 5445 ) / 3

LCM(21,5445) = 114345 / 3

LCM(21,5445) = 38115

∴ Least Common Multiple of 21,5445 is 38115

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

• LCM of 44, 7356
• LCM of 34, 7496
• LCM of 64, 4129
• LCM of 80, 8378
