Given numbers are 689,470,572,299,391

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

The LCM of 689,470,572,299,391 is 2785585660.

Find LCM of 689,470,572,299,391 with Prime Factorization

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

2 x 13 x 23 x 53 x 235 x 22 x 1 x 17 = 2785585660

Therefore, the lowest common multiple of 689,470,572,299,391 is 2785585660.

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.

689 x 470 x 572 x 299 x 391 = 21655142920840

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.

689 : 1, 13, 53, 689

470 : 1, 2, 5, 10, 47, 94, 235, 470

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

299 : 1, 13, 23, 299

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,470,572,299,391, is 1.

Now, the common factors can be found like this.

689:13x 53

470:2x 5x 47

572:2x 2x 11x 13

299:13x 23

391:17x 23

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

2x 13x 13x 23 = 7774

Therefore, the value for common factors is 7774.

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 = 21655142920840/(1x7774)

LCM = 21655142920840/7774

LCM = 2785585660

Thus, we can understand that the LCM of 689,470,572,299,391 is 2785585660.
