Given numbers are 678,117,813,217

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

The LCM of 678,117,813,217 is 1554974694.

Find LCM of 678,117,813,217 with Prime Factorization

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

3 x 226 x 39 x 271 x 217 = 1554974694

Therefore, the lowest common multiple of 678,117,813,217 is 1554974694.

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.

678 x 117 x 813 x 217 = 13994772246

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

117 : 1, 3, 9, 13, 39, 117

813 : 1, 3, 271, 813

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,117,813,217, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

117:3x 3x 13

813:3x 271

217:7x 31

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 13994772246/(1x9)

LCM = 13994772246/9

LCM = 1554974694

Thus, we can understand that the LCM of 678,117,813,217 is 1554974694.
