Given numbers are 634,766,621,687

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

The LCM of 634,766,621,687 is 34531473798.

Find LCM of 634,766,621,687 with Prime Factorization

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

2 x 3 x 317 x 383 x 207 x 229 = 34531473798

Therefore, the lowest common multiple of 634,766,621,687 is 34531473798.

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.

634 x 766 x 621 x 687 = 207188842788

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.

634 : 1, 2, 317, 634

766 : 1, 2, 383, 766

621 : 1, 3, 9, 23, 27, 69, 207, 621

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,766,621,687, is 1.

Now, the common factors can be found like this.

634:2x 317

766:2x 383

621:3x 3x 3x 23

687:3x 229

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 207188842788/(1x6)

LCM = 207188842788/6

LCM = 34531473798

Thus, we can understand that the LCM of 634,766,621,687 is 34531473798.
