Given numbers are 517,638,862,445

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

The LCM of 517,638,862,445 is 5751164870.

Find LCM of 517,638,862,445 with Prime Factorization

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

2 x 11 x 47 x 29 x 431 x 445 = 5751164870

Therefore, the lowest common multiple of 517,638,862,445 is 5751164870.

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.

517 x 638 x 862 x 445 = 126525627140

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.

517 : 1, 11, 47, 517

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

862 : 1, 2, 431, 862

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,638,862,445, is 1.

Now, the common factors can be found like this.

517:11x 47

638:2x 11x 29

862:2x 431

445:5x 89

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 126525627140/(1x22)

LCM = 126525627140/22

LCM = 5751164870

Thus, we can understand that the LCM of 517,638,862,445 is 5751164870.
