Least Common Multiple of 40, 10, 7, 10

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

• Least Common Multiple of 40, 10, 7, 10 by common division method
• Least Common Multiple of 40, 10, 7, 10 with GCF Formula

∴ So the LCM of the given numbers is 2 x 5 x 4 x 1 x 7 x 1 = 280

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 40,10,7,10 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,10,7,10) = 1

common factors(in case of two or more numbers have common factors) = 100

GCF(40,10,7,10) x common factors =1 x 100 = 100

LCM(40,10,7,10) = ( 40 × 10 × 7 × 10 ) / 100

LCM(40,10,7,10) = 28000 / 100

LCM(40,10,7,10) = 280

∴ Least Common Multiple of 40,10,7,10 is 280

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

• LCM of 12, 64, 7, 21
• LCM of 15, 38, 1, 37
• LCM of 90, 48, 5, 90
• LCM of 91, 85, 6, 79
• LCM of 46, 82, 9, 58

3. How to Find the LCM of 40, 10, 7, 10 ?

Least Common Multiple of 40, 10, 7, 10.

Step 1: Divide all the numbers with common prime numbers having remainder zero.

Step 2: Then multiply all the prime factors with last row quotient of common division that is LCM(40, 10, 7, 10) = 2 x 2 x 2 x 5 x 7 = 280.
