Given numbers are 909,386,641,687

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

The LCM of 909,386,641,687 is 51504443586.

Find LCM of 909,386,641,687 with Prime Factorization

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

3 x 303 x 386 x 641 x 229 = 51504443586

Therefore, the lowest common multiple of 909,386,641,687 is 51504443586.

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.

909 x 386 x 641 x 687 = 154513330758

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.

909 : 1, 3, 9, 101, 303, 909

386 : 1, 2, 193, 386

641 : 1, 641

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,386,641,687, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

386:2x 193

641:641

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 154513330758/(1x3)

LCM = 154513330758/3

LCM = 51504443586

Thus, we can understand that the LCM of 909,386,641,687 is 51504443586.
