Given numbers are 407,466,687,638

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

The LCM of 407,466,687,638 is 3778636026.

Find LCM of 407,466,687,638 with Prime Factorization

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

2 x 11 x 37 x 233 x 687 x 29 = 3778636026

Therefore, the lowest common multiple of 407,466,687,638 is 3778636026.

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.

407 x 466 x 687 x 638 = 83129992572

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.

407 : 1, 11, 37, 407

466 : 1, 2, 233, 466

687 : 1, 3, 229, 687

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,466,687,638, is 1.

Now, the common factors can be found like this.

407:11x 37

466:2x 233

687:3x 229

638:2x 11x 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 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 = 83129992572/(1x22)

LCM = 83129992572/22

LCM = 3778636026

Thus, we can understand that the LCM of 407,466,687,638 is 3778636026.
