Given numbers are 621,682,187,554

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

The LCM of 621,682,187,554 is 1994365098.

Find LCM of 621,682,187,554 with Prime Factorization

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

2 x 11 x 621 x 31 x 17 x 277 = 1994365098

Therefore, the lowest common multiple of 621,682,187,554 is 1994365098.

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.

621 x 682 x 187 x 554 = 43876032156

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

682 : 1, 2, 11, 22, 31, 62, 341, 682

187 : 1, 11, 17, 187

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,682,187,554, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

682:2x 11x 31

187:11x 17

554:2x 277

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 43876032156/(1x22)

LCM = 43876032156/22

LCM = 1994365098

Thus, we can understand that the LCM of 621,682,187,554 is 1994365098.
