Given numbers are 436,520,394,842

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

The LCM of 436,520,394,842 is 4700869160.

Find LCM of 436,520,394,842 with Prime Factorization

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

2 x 2 x 109 x 130 x 197 x 421 = 4700869160

Therefore, the lowest common multiple of 436,520,394,842 is 4700869160.

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.

436 x 520 x 394 x 842 = 75213906560

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.

436 : 1, 2, 4, 109, 218, 436

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

394 : 1, 2, 197, 394

842 : 1, 2, 421, 842

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,520,394,842, is 2.

Now, the common factors can be found like this.

436:2x 2x 109

520:2x 2x 2x 5x 13

394:2x 197

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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 75213906560/(2x8)

LCM = 75213906560/16

LCM = 4700869160

Thus, we can understand that the LCM of 436,520,394,842 is 4700869160.
