Given numbers are 394,664,217,987

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

The LCM of 394,664,217,987 is 4002332376.

Find LCM of 394,664,217,987 with Prime Factorization

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

2 x 7 x 197 x 332 x 31 x 141 = 4002332376

Therefore, the lowest common multiple of 394,664,217,987 is 4002332376.

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.

394 x 664 x 217 x 987 = 56032653264

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.

394 : 1, 2, 197, 394

664 : 1, 2, 4, 8, 83, 166, 332, 664

217 : 1, 7, 31, 217

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,664,217,987, is 1.

Now, the common factors can be found like this.

394:2x 197

664:2x 2x 2x 83

217:7x 31

987:3x 7x 47

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 56032653264/(1x14)

LCM = 56032653264/14

LCM = 4002332376

Thus, we can understand that the LCM of 394,664,217,987 is 4002332376.
