Given numbers are 665,394,422,979

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

The LCM of 665,394,422,979 is 54123143690.

Find LCM of 665,394,422,979 with Prime Factorization

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

2 x 665 x 197 x 211 x 979 = 54123143690

Therefore, the lowest common multiple of 665,394,422,979 is 54123143690.

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.

665 x 394 x 422 x 979 = 108246287380

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

394 : 1, 2, 197, 394

422 : 1, 2, 211, 422

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,394,422,979, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

394:2x 197

422:2x 211

979:11x 89

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 = 108246287380/(1x2)

LCM = 108246287380/2

LCM = 54123143690

Thus, we can understand that the LCM of 665,394,422,979 is 54123143690.
