Given numbers are 581,400,391,348

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

The LCM of 581,400,391,348 is 7905550800.

Find LCM of 581,400,391,348 with Prime Factorization

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

2 x 2 x 581 x 100 x 391 x 87 = 7905550800

Therefore, the lowest common multiple of 581,400,391,348 is 7905550800.

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 400 x 391 x 348 = 31622203200

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

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

391 : 1, 17, 23, 391

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,400,391,348, is 1.

Now, the common factors can be found like this.

581:7x 83

400:2x 2x 2x 2x 5x 5

391:17x 23

348:2x 2x 3x 29

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 = 31622203200/(1x4)

LCM = 31622203200/4

LCM = 7905550800

Thus, we can understand that the LCM of 581,400,391,348 is 7905550800.
