Given numbers are 617,430,547,172

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

The LCM of 617,430,547,172 is 290249140.

Find LCM of 617,430,547,172 with Prime Factorization

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

2 x 43 x 617 x 5 x 547 x 2 = 290249140

Therefore, the lowest common multiple of 617,430,547,172 is 290249140.

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.

617 x 430 x 547 x 172 = 24961426040

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.

617 : 1, 617

430 : 1, 2, 5, 10, 43, 86, 215, 430

547 : 1, 547

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,430,547,172, is 1.

Now, the common factors can be found like this.

617:617

430:2x 5x 43

547:547

172:2x 2x 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 43 = 86

Therefore, the value for common factors is 86.

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 = 24961426040/(1x86)

LCM = 24961426040/86

LCM = 290249140

Thus, we can understand that the LCM of 617,430,547,172 is 290249140.
