Calculate the LCM of 312,687,505,540

Given numbers are 312,687,505,540

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 312,687,505,540 is 324731160.

Find LCM of 312,687,505,540 with Prime Factorization


2 312, 687, 505, 540
2 156, 687, 505, 270
3 78, 687, 505, 135
5 26, 229, 505, 45
26, 229, 101, 9

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 5 x 26 x 229 x 101 x 9 = 324731160

Therefore, the lowest common multiple of 312,687,505,540 is 324731160.

LCM Formula to Find Lowest Common Multiple of 312,687,505,540

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

312 x 687 x 505 x 540 = 58451608800

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

687 : 1, 3, 229, 687

505 : 1, 5, 101, 505

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,687,505,540, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

687:3x 229

505:5x 101

540:2x 2x 3x 3x 3x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 58451608800/(1x180)

LCM = 58451608800/180

LCM = 324731160

Thus, we can understand that the LCM of 312,687,505,540 is 324731160.
