Given numbers are 181,464,979,180,391

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

The LCM of 181,464,979,180,391 is 1446666811920.

Find LCM of 181,464,979,180,391 with Prime Factorization

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

2 x 2 x 181 x 116 x 979 x 45 x 391 = 1446666811920

Therefore, the lowest common multiple of 181,464,979,180,391 is 1446666811920.

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.

181 x 464 x 979 x 180 x 391 = 5786667247680

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.

181 : 1, 181

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

979 : 1, 11, 89, 979

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,464,979,180,391, is 1.

Now, the common factors can be found like this.

181:181

464:2x 2x 2x 2x 29

979:11x 89

180:2x 2x 3x 3x 5

391:17x 23

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 = 5786667247680/(1x4)

LCM = 5786667247680/4

LCM = 1446666811920

Thus, we can understand that the LCM of 181,464,979,180,391 is 1446666811920.
