Given numbers are 516,406,520

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

The LCM of 516,406,520 is 13617240.

Find LCM of 516,406,520 with Prime Factorization

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

2 x 2 x 129 x 203 x 130 = 13617240

Therefore, the lowest common multiple of 516,406,520 is 13617240.

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.

516 x 406 x 520 = 108937920

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.

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

406 : 1, 2, 7, 14, 29, 58, 203, 406

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,406,520, is 2.

Now, the common factors can be found like this.

516:2x 2x 3x 43

406:2x 7x 29

520:2x 2x 2x 5x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 108937920/(2x4)

LCM = 108937920/8

LCM = 13617240

Thus, we can understand that the LCM of 516,406,520 is 13617240.

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