Given numbers are 818,215,653,520

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

The LCM of 818,215,653,520 is 5971841720.

Find LCM of 818,215,653,520 with Prime Factorization

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

2 x 5 x 409 x 43 x 653 x 52 = 5971841720

Therefore, the lowest common multiple of 818,215,653,520 is 5971841720.

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.

818 x 215 x 653 x 520 = 59718417200

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.

818 : 1, 2, 409, 818

215 : 1, 5, 43, 215

653 : 1, 653

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,215,653,520, is 1.

Now, the common factors can be found like this.

818:2x 409

215:5x 43

653:653

520:2x 2x 2x 5x 13

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 59718417200/(1x10)

LCM = 59718417200/10

LCM = 5971841720

Thus, we can understand that the LCM of 818,215,653,520 is 5971841720.
