Given numbers are 398,718,698,102,698

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

The LCM of 398,718,698,102,698 is 2543156718.

Find LCM of 398,718,698,102,698 with Prime Factorization

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

2 x 349 x 199 x 359 x 1 x 51 x 1 = 2543156718

Therefore, the lowest common multiple of 398,718,698,102,698 is 2543156718.

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 718 x 698 x 102 x 698 = 14200987113312

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

718 : 1, 2, 359, 718

698 : 1, 2, 349, 698

102 : 1, 2, 3, 6, 17, 34, 51, 102

698 : 1, 2, 349, 698

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,718,698,102,698, is 2.

Now, the common factors can be found like this.

398:2x 199

718:2x 359

698:2x 349

102:2x 3x 17

698:2x 349

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 2x 349 = 2792

Therefore, the value for common factors is 2792.

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 = 14200987113312/(2x2792)

LCM = 14200987113312/5584

LCM = 2543156718

Thus, we can understand that the LCM of 398,718,698,102,698 is 2543156718.
