Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 15, 16, 51, 45 i.e. 12240 smallest integer divisible by all numbers.
Least common multiple (LCM) of 15, 16, 51, 45 is 12240.
LCM(15, 16, 51, 45) = 12240
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 15, 16, 51, 45 |
5 | 5, 16, 17, 15 |
1, 16, 17, 3 |
∴ So the LCM of the given numbers is 3 x 5 x 1 x 16 x 17 x 3 = 12240
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 15,16,51,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,16,51,45) = 1
common factors(in case of two or more numbers have common factors) = 45
GCF(15,16,51,45) x common factors =1 x 45 = 45
LCM(15,16,51,45) = ( 15 × 16 × 51 × 45 ) / 45
LCM(15,16,51,45) = 550800 / 45
LCM(15,16,51,45) = 12240
∴ Least Common Multiple of 15,16,51,45 is 12240
Here are some samples of LCM of two or more Numbers calculations.
1. What is the LCM of 15, 16, 51, 45?

3. How to Find the LCM of 15, 16, 51, 45 ?
Least Common Multiple of 15, 16, 51, 45.
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(15, 16, 51, 45) = 2 x 2 x 2 x 2 x 3 x 3 x 5 x 17 = 12240.
