Given numbers are 394,340,745,998

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

The LCM of 394,340,745,998 is 4980029980.

Find LCM of 394,340,745,998 with Prime Factorization

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

2 x 5 x 197 x 34 x 149 x 499 = 4980029980

Therefore, the lowest common multiple of 394,340,745,998 is 4980029980.

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.

394 x 340 x 745 x 998 = 99600599600

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.

394 : 1, 2, 197, 394

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

745 : 1, 5, 149, 745

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,340,745,998, is 1.

Now, the common factors can be found like this.

394:2x 197

340:2x 2x 5x 17

745:5x 149

998:2x 499

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 5 = 20

Therefore, the value for common factors is 20.

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 = 99600599600/(1x20)

LCM = 99600599600/20

LCM = 4980029980

Thus, we can understand that the LCM of 394,340,745,998 is 4980029980.
