Given numbers are 626,860,686,689

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

The LCM of 626,860,686,689 is 63614501860.

Find LCM of 626,860,686,689 with Prime Factorization

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

2 x 313 x 430 x 343 x 689 = 63614501860

Therefore, the lowest common multiple of 626,860,686,689 is 63614501860.

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.

626 x 860 x 686 x 689 = 254458007440

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.

626 : 1, 2, 313, 626

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

686 : 1, 2, 7, 14, 49, 98, 343, 686

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,860,686,689, is 1.

Now, the common factors can be found like this.

626:2x 313

860:2x 2x 5x 43

686:2x 7x 7x 7

689:13x 53

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 = 254458007440/(1x4)

LCM = 254458007440/4

LCM = 63614501860

Thus, we can understand that the LCM of 626,860,686,689 is 63614501860.
