Given numbers are 187,857,161,561

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

The LCM of 187,857,161,561 is 77405097.

Find LCM of 187,857,161,561 with Prime Factorization

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

11 x 17 x 1 x 857 x 161 x 3 = 77405097

Therefore, the lowest common multiple of 187,857,161,561 is 77405097.

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.

187 x 857 x 161 x 561 = 14474753139

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.

187 : 1, 11, 17, 187

857 : 1, 857

161 : 1, 7, 23, 161

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,857,161,561, is 1.

Now, the common factors can be found like this.

187:11x 17

857:857

161:7x 23

561:3x 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.

11x 17 = 187

Therefore, the value for common factors is 187.

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 = 14474753139/(1x187)

LCM = 14474753139/187

LCM = 77405097

Thus, we can understand that the LCM of 187,857,161,561 is 77405097.
