Given numbers are 638,724,514,155

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

The LCM of 638,724,514,155 is 9200132260.

Find LCM of 638,724,514,155 with Prime Factorization

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

2 x 319 x 362 x 257 x 155 = 9200132260

Therefore, the lowest common multiple of 638,724,514,155 is 9200132260.

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.

638 x 724 x 514 x 155 = 36800529040

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

724 : 1, 2, 4, 181, 362, 724

514 : 1, 2, 257, 514

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,724,514,155, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

724:2x 2x 181

514:2x 257

155:5x 31

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 = 36800529040/(1x4)

LCM = 36800529040/4

LCM = 9200132260

Thus, we can understand that the LCM of 638,724,514,155 is 9200132260.
