Given numbers are 515,390,556,331

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

The LCM of 515,390,556,331 is 3696363060.

Find LCM of 515,390,556,331 with Prime Factorization

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

2 x 5 x 103 x 39 x 278 x 331 = 3696363060

Therefore, the lowest common multiple of 515,390,556,331 is 3696363060.

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.

515 x 390 x 556 x 331 = 36963630600

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.

515 : 1, 5, 103, 515

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

556 : 1, 2, 4, 139, 278, 556

331 : 1, 331

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,390,556,331, is 1.

Now, the common factors can be found like this.

515:5x 103

390:2x 3x 5x 13

556:2x 2x 139

331:331

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 36963630600/(1x10)

LCM = 36963630600/10

LCM = 3696363060

Thus, we can understand that the LCM of 515,390,556,331 is 3696363060.
