Given numbers are 854,818,638,645

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

The LCM of 854,818,638,645 is 71867340930.

Find LCM of 854,818,638,645 with Prime Factorization

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

2 x 427 x 409 x 319 x 645 = 71867340930

Therefore, the lowest common multiple of 854,818,638,645 is 71867340930.

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.

854 x 818 x 638 x 645 = 287469363720

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

818 : 1, 2, 409, 818

638 : 1, 2, 11, 22, 29, 58, 319, 638

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,818,638,645, is 1.

Now, the common factors can be found like this.

854:2x 7x 61

818:2x 409

638:2x 11x 29

645:3x 5x 43

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 = 287469363720/(1x4)

LCM = 287469363720/4

LCM = 71867340930

Thus, we can understand that the LCM of 854,818,638,645 is 71867340930.
