Given numbers are 731,172,639,841

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

The LCM of 731,172,639,841 is 1571354676.

Find LCM of 731,172,639,841 with Prime Factorization

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

43 x 17 x 4 x 639 x 841 = 1571354676

Therefore, the lowest common multiple of 731,172,639,841 is 1571354676.

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.

731 x 172 x 639 x 841 = 67568251068

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.

731 : 1, 17, 43, 731

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

639 : 1, 3, 9, 71, 213, 639

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,172,639,841, is 1.

Now, the common factors can be found like this.

731:17x 43

172:2x 2x 43

639:3x 3x 71

841:29x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

43 = 43

Therefore, the value for common factors is 43.

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 = 67568251068/(1x43)

LCM = 67568251068/43

LCM = 1571354676

Thus, we can understand that the LCM of 731,172,639,841 is 1571354676.
