Given numbers are 646,939,856,540,214

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

The LCM of 646,939,856,540,214 is 11683000440.

Find LCM of 646,939,856,540,214 with Prime Factorization

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

2 x 2 x 3 x 107 x 323 x 313 x 2 x 45 x 1 = 11683000440

Therefore, the lowest common multiple of 646,939,856,540,214 is 11683000440.

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.

646 x 939 x 856 x 540 x 214 = 60003890259840

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

939 : 1, 3, 313, 939

856 : 1, 2, 4, 8, 107, 214, 428, 856

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,939,856,540,214, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

939:3x 313

856:2x 2x 2x 107

540:2x 2x 3x 3x 3x 5

214:2x 107

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

2x 2x 2x 2x 3x 107 = 5136

Therefore, the value for common factors is 5136.

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 = 60003890259840/(1x5136)

LCM = 60003890259840/5136

LCM = 11683000440

Thus, we can understand that the LCM of 646,939,856,540,214 is 11683000440.
