Given numbers are 481,836,421,218

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

The LCM of 481,836,421,218 is 18452701124.

Find LCM of 481,836,421,218 with Prime Factorization

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

2 x 481 x 418 x 421 x 109 = 18452701124

Therefore, the lowest common multiple of 481,836,421,218 is 18452701124.

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.

481 x 836 x 421 x 218 = 36905402248

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.

481 : 1, 13, 37, 481

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

421 : 1, 421

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,836,421,218, is 1.

Now, the common factors can be found like this.

481:13x 37

836:2x 2x 11x 19

421:421

218:2x 109

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

2 = 2

Therefore, the value for common factors is 2.

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 = 36905402248/(1x2)

LCM = 36905402248/2

LCM = 18452701124

Thus, we can understand that the LCM of 481,836,421,218 is 18452701124.
