Given numbers are 998,790,231,394

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

The LCM of 998,790,231,394 is 17939314470.

Find LCM of 998,790,231,394 with Prime Factorization

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

2 x 499 x 395 x 231 x 197 = 17939314470

Therefore, the lowest common multiple of 998,790,231,394 is 17939314470.

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.

998 x 790 x 231 x 394 = 71757257880

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.

998 : 1, 2, 499, 998

790 : 1, 2, 5, 10, 79, 158, 395, 790

231 : 1, 3, 7, 11, 21, 33, 77, 231

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,790,231,394, is 1.

Now, the common factors can be found like this.

998:2x 499

790:2x 5x 79

231:3x 7x 11

394:2x 197

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 = 71757257880/(1x4)

LCM = 71757257880/4

LCM = 17939314470

Thus, we can understand that the LCM of 998,790,231,394 is 17939314470.
