Calculate the LCM of 998,752,173,338,638

Given numbers are 998,752,173,338,638

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

The LCM of 998,752,173,338,638 is 3499789122544.

Find LCM of 998,752,173,338,638 with Prime Factorization


2 998, 752, 173, 338, 638
499, 376, 173, 169, 319

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

2 x 499 x 376 x 173 x 169 x 319 = 3499789122544

Therefore, the lowest common multiple of 998,752,173,338,638 is 3499789122544.

LCM Formula to Find Lowest Common Multiple of 998,752,173,338,638

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.

998 x 752 x 173 x 338 x 638 = 27998312980352

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.

998 : 1, 2, 499, 998

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

173 : 1, 173

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,752,173,338,638, is 1.

Now, the common factors can be found like this.

998:2x 499

752:2x 2x 2x 2x 47

173:173

338:2x 13x 13

638:2x 11x 29

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 27998312980352/(1x8)

LCM = 27998312980352/8

LCM = 3499789122544

Thus, we can understand that the LCM of 998,752,173,338,638 is 3499789122544.
