Given numbers are 163,720,682,187

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

The LCM of 163,720,682,187 is 680335920.

Find LCM of 163,720,682,187 with Prime Factorization

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

2 x 11 x 163 x 360 x 31 x 17 = 680335920

Therefore, the lowest common multiple of 163,720,682,187 is 680335920.

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.

163 x 720 x 682 x 187 = 14967390240

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.

163 : 1, 163

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

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

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,720,682,187, is 1.

Now, the common factors can be found like this.

163:163

720:2x 2x 2x 2x 3x 3x 5

682:2x 11x 31

187:11x 17

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 = 14967390240/(1x22)

LCM = 14967390240/22

LCM = 680335920

Thus, we can understand that the LCM of 163,720,682,187 is 680335920.
