Given numbers are 392,790,353,579,991

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

The LCM of 392,790,353,579,991 is 31362457532280.

Find LCM of 392,790,353,579,991 with Prime Factorization

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

2 x 196 x 395 x 353 x 579 x 991 = 31362457532280

Therefore, the lowest common multiple of 392,790,353,579,991 is 31362457532280.

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.

392 x 790 x 353 x 579 x 991 = 62724915064560

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

790 : 1, 2, 5, 10, 79, 158, 395, 790

353 : 1, 353

579 : 1, 3, 193, 579

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,790,353,579,991, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

790:2x 5x 79

353:353

579:3x 193

991:991

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 = 62724915064560/(1x2)

LCM = 62724915064560/2

LCM = 31362457532280

Thus, we can understand that the LCM of 392,790,353,579,991 is 31362457532280.
