Given numbers are 581,343,642,320

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

The LCM of 581,343,642,320 is 2924335680.

Find LCM of 581,343,642,320 with Prime Factorization

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

2 x 7 x 83 x 49 x 321 x 160 = 2924335680

Therefore, the lowest common multiple of 581,343,642,320 is 2924335680.

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.

581 x 343 x 642 x 320 = 40940699520

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.

581 : 1, 7, 83, 581

343 : 1, 7, 49, 343

642 : 1, 2, 3, 6, 107, 214, 321, 642

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,343,642,320, is 1.

Now, the common factors can be found like this.

581:7x 83

343:7x 7x 7

642:2x 3x 107

320:2x 2x 2x 2x 2x 2x 5

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 40940699520/(1x14)

LCM = 40940699520/14

LCM = 2924335680

Thus, we can understand that the LCM of 581,343,642,320 is 2924335680.
