Calculate the LCM of 638,581,470,608

Given numbers are 638,581,470,608

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

The LCM of 638,581,470,608 is 26481236320.

Find LCM of 638,581,470,608 with Prime Factorization


2 638, 581, 470, 608
319, 581, 235, 304

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

2 x 319 x 581 x 235 x 304 = 26481236320

Therefore, the lowest common multiple of 638,581,470,608 is 26481236320.

LCM Formula to Find Lowest Common Multiple of 638,581,470,608

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 581 x 470 x 608 = 105924945280

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

581 : 1, 7, 83, 581

470 : 1, 2, 5, 10, 47, 94, 235, 470

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,581,470,608, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

581:7x 83

470:2x 5x 47

608:2x 2x 2x 2x 2x 19

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 = 105924945280/(1x4)

LCM = 105924945280/4

LCM = 26481236320

Thus, we can understand that the LCM of 638,581,470,608 is 26481236320.
