Given numbers are 638,521,386,106

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

The LCM of 638,521,386,106 is 3400099142.

Find LCM of 638,521,386,106 with Prime Factorization

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

2 x 319 x 521 x 193 x 53 = 3400099142

Therefore, the lowest common multiple of 638,521,386,106 is 3400099142.

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 521 x 386 x 106 = 13600396568

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

521 : 1, 521

386 : 1, 2, 193, 386

106 : 1, 2, 53, 106

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,521,386,106, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

521:521

386:2x 193

106:2x 53

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 = 13600396568/(1x4)

LCM = 13600396568/4

LCM = 3400099142

Thus, we can understand that the LCM of 638,521,386,106 is 3400099142.
