Given numbers are 398,699,998,171

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

The LCM of 398,699,998,171 is 7912899486.

Find LCM of 398,699,998,171 with Prime Factorization

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

2 x 3 x 199 x 233 x 499 x 57 = 7912899486

Therefore, the lowest common multiple of 398,699,998,171 is 7912899486.

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 699 x 998 x 171 = 47477396916

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

699 : 1, 3, 233, 699

998 : 1, 2, 499, 998

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,699,998,171, is 1.

Now, the common factors can be found like this.

398:2x 199

699:3x 233

998:2x 499

171:3x 3x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 47477396916/(1x6)

LCM = 47477396916/6

LCM = 7912899486

Thus, we can understand that the LCM of 398,699,998,171 is 7912899486.
