Given numbers are 398,715,894,854

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

The LCM of 398,715,894,854 is 54315591330.

Find LCM of 398,715,894,854 with Prime Factorization

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

2 x 199 x 715 x 447 x 427 = 54315591330

Therefore, the lowest common multiple of 398,715,894,854 is 54315591330.

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.

398 x 715 x 894 x 854 = 217262365320

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.

398 : 1, 2, 199, 398

715 : 1, 5, 11, 13, 55, 65, 143, 715

894 : 1, 2, 3, 6, 149, 298, 447, 894

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,715,894,854, is 1.

Now, the common factors can be found like this.

398:2x 199

715:5x 11x 13

894:2x 3x 149

854:2x 7x 61

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 = 217262365320/(1x4)

LCM = 217262365320/4

LCM = 54315591330

Thus, we can understand that the LCM of 398,715,894,854 is 54315591330.
