Given numbers are 172,842,722,645

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

The LCM of 172,842,722,645 is 392110980.

Find LCM of 172,842,722,645 with Prime Factorization

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

2 x 43 x 2 x 421 x 361 x 15 = 392110980

Therefore, the lowest common multiple of 172,842,722,645 is 392110980.

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 842 x 722 x 645 = 67443088560

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

842 : 1, 2, 421, 842

722 : 1, 2, 19, 38, 361, 722

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,842,722,645, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

842:2x 421

722:2x 19x 19

645:3x 5x 43

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 43 = 172

Therefore, the value for common factors is 172.

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 = 67443088560/(1x172)

LCM = 67443088560/172

LCM = 392110980

Thus, we can understand that the LCM of 172,842,722,645 is 392110980.
