Given numbers are 128,713,186,845

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

The LCM of 128,713,186,845 is 231354240.

Find LCM of 128,713,186,845 with Prime Factorization

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

2 x 31 x 64 x 23 x 3 x 845 = 231354240

Therefore, the lowest common multiple of 128,713,186,845 is 231354240.

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.

128 x 713 x 186 x 845 = 14343962880

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

713 : 1, 23, 31, 713

186 : 1, 2, 3, 6, 31, 62, 93, 186

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,713,186,845, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

713:23x 31

186:2x 3x 31

845:5x 13x 13

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 14343962880/(1x62)

LCM = 14343962880/62

LCM = 231354240

Thus, we can understand that the LCM of 128,713,186,845 is 231354240.
