Given numbers are 731,451,638,874

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

The LCM of 731,451,638,874 is 8356094626.

Find LCM of 731,451,638,874 with Prime Factorization

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

2 x 11 x 731 x 41 x 29 x 437 = 8356094626

Therefore, the lowest common multiple of 731,451,638,874 is 8356094626.

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 451 x 638 x 874 = 183834081772

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

451 : 1, 11, 41, 451

638 : 1, 2, 11, 22, 29, 58, 319, 638

874 : 1, 2, 19, 23, 38, 46, 437, 874

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,451,638,874, is 1.

Now, the common factors can be found like this.

731:17x 43

451:11x 41

638:2x 11x 29

874:2x 19x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 183834081772/(1x22)

LCM = 183834081772/22

LCM = 8356094626

Thus, we can understand that the LCM of 731,451,638,874 is 8356094626.
