Given numbers are 391,230,943,998

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

The LCM of 391,230,943,998 is 79994690.

Find LCM of 391,230,943,998 with Prime Factorization

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

2 x 23 x 17 x 5 x 41 x 499 = 79994690

Therefore, the lowest common multiple of 391,230,943,998 is 79994690.

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.

391 x 230 x 943 x 998 = 84634382020

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.

391 : 1, 17, 23, 391

230 : 1, 2, 5, 10, 23, 46, 115, 230

943 : 1, 23, 41, 943

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,230,943,998, is 1.

Now, the common factors can be found like this.

391:17x 23

230:2x 5x 23

943:23x 41

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 23x 23 = 1058

Therefore, the value for common factors is 1058.

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 = 84634382020/(1x1058)

LCM = 84634382020/1058

LCM = 79994690

Thus, we can understand that the LCM of 391,230,943,998 is 79994690.
