Given numbers are 752,138,638,563

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

The LCM of 752,138,638,563 is 9318929136.

Find LCM of 752,138,638,563 with Prime Factorization

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

2 x 376 x 69 x 319 x 563 = 9318929136

Therefore, the lowest common multiple of 752,138,638,563 is 9318929136.

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.

752 x 138 x 638 x 563 = 37275716544

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.

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

138 : 1, 2, 3, 6, 23, 46, 69, 138

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

563 : 1, 563

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 752,138,638,563, is 1.

Now, the common factors can be found like this.

752:2x 2x 2x 2x 47

138:2x 3x 23

638:2x 11x 29

563:563

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 = 37275716544/(1x4)

LCM = 37275716544/4

LCM = 9318929136

Thus, we can understand that the LCM of 752,138,638,563 is 9318929136.
