Calculate the LCM of 358,689,817,872

Given numbers are 358,689,817,872

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

The LCM of 358,689,817,872 is 87863964344.

Find LCM of 358,689,817,872 with Prime Factorization


2 358, 689, 817, 872
179, 689, 817, 436

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

2 x 179 x 689 x 817 x 436 = 87863964344

Therefore, the lowest common multiple of 358,689,817,872 is 87863964344.

LCM Formula to Find Lowest Common Multiple of 358,689,817,872

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.

358 x 689 x 817 x 872 = 175727928688

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.

358 : 1, 2, 179, 358

689 : 1, 13, 53, 689

817 : 1, 19, 43, 817

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,689,817,872, is 1.

Now, the common factors can be found like this.

358:2x 179

689:13x 53

817:19x 43

872:2x 2x 2x 109

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 = 175727928688/(1x2)

LCM = 175727928688/2

LCM = 87863964344

Thus, we can understand that the LCM of 358,689,817,872 is 87863964344.
