Given numbers are 398,694,173,698

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

The LCM of 398,694,173,698 is 8338425962.

Find LCM of 398,694,173,698 with Prime Factorization

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

2 x 199 x 347 x 173 x 349 = 8338425962

Therefore, the lowest common multiple of 398,694,173,698 is 8338425962.

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 694 x 173 x 698 = 33353703848

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

694 : 1, 2, 347, 694

173 : 1, 173

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,694,173,698, is 1.

Now, the common factors can be found like this.

398:2x 199

694:2x 347

173:173

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 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 = 33353703848/(1x4)

LCM = 33353703848/4

LCM = 8338425962

Thus, we can understand that the LCM of 398,694,173,698 is 8338425962.
