Given numbers are 172,779,111,580

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

The LCM of 172,779,111,580 is 2156536860.

Find LCM of 172,779,111,580 with Prime Factorization

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

2 x 2 x 43 x 779 x 111 x 145 = 2156536860

Therefore, the lowest common multiple of 172,779,111,580 is 2156536860.

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.

172 x 779 x 111 x 580 = 8626147440

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.

172 : 1, 2, 4, 43, 86, 172

779 : 1, 19, 41, 779

111 : 1, 3, 37, 111

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,779,111,580, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

779:19x 41

111:3x 37

580:2x 2x 5x 29

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 = 8626147440/(1x4)

LCM = 8626147440/4

LCM = 2156536860

Thus, we can understand that the LCM of 172,779,111,580 is 2156536860.
