Given numbers are 168,695,394,391

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

The LCM of 168,695,394,391 is 8993672520.

Find LCM of 168,695,394,391 with Prime Factorization

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

2 x 84 x 695 x 197 x 391 = 8993672520

Therefore, the lowest common multiple of 168,695,394,391 is 8993672520.

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.

168 x 695 x 394 x 391 = 17987345040

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

695 : 1, 5, 139, 695

394 : 1, 2, 197, 394

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,695,394,391, is 1.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

695:5x 139

394:2x 197

391:17x 23

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 = 17987345040/(1x2)

LCM = 17987345040/2

LCM = 8993672520

Thus, we can understand that the LCM of 168,695,394,391 is 8993672520.
