Given numbers are 515,284,808,921

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

The LCM of 515,284,808,921 is 27210502920.

Find LCM of 515,284,808,921 with Prime Factorization

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

2 x 2 x 515 x 71 x 202 x 921 = 27210502920

Therefore, the lowest common multiple of 515,284,808,921 is 27210502920.

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.

515 x 284 x 808 x 921 = 108842011680

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.

515 : 1, 5, 103, 515

284 : 1, 2, 4, 71, 142, 284

808 : 1, 2, 4, 8, 101, 202, 404, 808

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,284,808,921, is 1.

Now, the common factors can be found like this.

515:5x 103

284:2x 2x 71

808:2x 2x 2x 101

921:3x 307

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 108842011680/(1x4)

LCM = 108842011680/4

LCM = 27210502920

Thus, we can understand that the LCM of 515,284,808,921 is 27210502920.
