Given numbers are 398,538,698,847

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

The LCM of 398,538,698,847 is 31647848386.

Find LCM of 398,538,698,847 with Prime Factorization

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

2 x 199 x 269 x 349 x 847 = 31647848386

Therefore, the lowest common multiple of 398,538,698,847 is 31647848386.

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 538 x 698 x 847 = 126591393544

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

538 : 1, 2, 269, 538

698 : 1, 2, 349, 698

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,538,698,847, is 1.

Now, the common factors can be found like this.

398:2x 199

538:2x 269

698:2x 349

847:7x 11x 11

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 = 126591393544/(1x4)

LCM = 126591393544/4

LCM = 31647848386

Thus, we can understand that the LCM of 398,538,698,847 is 31647848386.
