Given numbers are 522,388,391,842

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

The LCM of 522,388,391,842 is 16669826748.

Find LCM of 522,388,391,842 with Prime Factorization

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

2 x 261 x 194 x 391 x 421 = 16669826748

Therefore, the lowest common multiple of 522,388,391,842 is 16669826748.

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.

522 x 388 x 391 x 842 = 66679306992

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.

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

388 : 1, 2, 4, 97, 194, 388

391 : 1, 17, 23, 391

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 522,388,391,842, is 1.

Now, the common factors can be found like this.

522:2x 3x 3x 29

388:2x 2x 97

391:17x 23

842:2x 421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 66679306992/(1x4)

LCM = 66679306992/4

LCM = 16669826748

Thus, we can understand that the LCM of 522,388,391,842 is 16669826748.
