Given numbers are 125,305,305,689

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

The LCM of 125,305,305,689 is 5253625.

Find LCM of 125,305,305,689 with Prime Factorization

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

5 x 61 x 25 x 1 x 1 x 689 = 5253625

Therefore, the lowest common multiple of 125,305,305,689 is 5253625.

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.

125 x 305 x 305 x 689 = 8011778125

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.

125 : 1, 5, 25, 125

305 : 1, 5, 61, 305

305 : 1, 5, 61, 305

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,305,305,689, is 1.

Now, the common factors can be found like this.

125:5x 5x 5

305:5x 61

305:5x 61

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.

5x 5x 61 = 1525

Therefore, the value for common factors is 1525.

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 = 8011778125/(1x1525)

LCM = 8011778125/1525

LCM = 5253625

Thus, we can understand that the LCM of 125,305,305,689 is 5253625.
