Given numbers are 638,277,338,623

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

The LCM of 638,277,338,623 is 18606950362.

Find LCM of 638,277,338,623 with Prime Factorization

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

2 x 319 x 277 x 169 x 623 = 18606950362

Therefore, the lowest common multiple of 638,277,338,623 is 18606950362.

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 277 x 338 x 623 = 37213900724

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

277 : 1, 277

338 : 1, 2, 13, 26, 169, 338

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,277,338,623, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

277:277

338:2x 13x 13

623:7x 89

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

2 = 2

Therefore, the value for common factors is 2.

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 = 37213900724/(1x2)

LCM = 37213900724/2

LCM = 18606950362

Thus, we can understand that the LCM of 638,277,338,623 is 18606950362.

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