Given numbers are 398,178,718,821

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

The LCM of 398,178,718,821 is 10440244858.

Find LCM of 398,178,718,821 with Prime Factorization

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

2 x 199 x 89 x 359 x 821 = 10440244858

Therefore, the lowest common multiple of 398,178,718,821 is 10440244858.

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 178 x 718 x 821 = 41760979432

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

178 : 1, 2, 89, 178

718 : 1, 2, 359, 718

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,178,718,821, is 1.

Now, the common factors can be found like this.

398:2x 199

178:2x 89

718:2x 359

821:821

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 = 41760979432/(1x4)

LCM = 41760979432/4

LCM = 10440244858

Thus, we can understand that the LCM of 398,178,718,821 is 10440244858.
