Given numbers are 398,620,442,995,815

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

The LCM of 398,620,442,995,815 is 4444517740.

Find LCM of 398,620,442,995,815 with Prime Factorization

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

2 x 5 x 199 x 1 x 62 x 221 x 1 x 163 = 4444517740

Therefore, the lowest common multiple of 398,620,442,995,815 is 4444517740.

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 620 x 442 x 995 x 815 = 88445903026000

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

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

442 : 1, 2, 13, 17, 26, 34, 221, 442

995 : 1, 5, 199, 995

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,620,442,995,815, is 1.

Now, the common factors can be found like this.

398:2x 199

620:2x 2x 5x 31

442:2x 13x 17

995:5x 199

815:5x 163

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 5x 5x 199 = 19900

Therefore, the value for common factors is 19900.

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 = 88445903026000/(1x19900)

LCM = 88445903026000/19900

LCM = 4444517740

Thus, we can understand that the LCM of 398,620,442,995,815 is 4444517740.
