Given numbers are 165,645,894,260,786

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

The LCM of 165,645,894,260,786 is 7201339860.

Find LCM of 165,645,894,260,786 with Prime Factorization

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

2 x 3 x 5 x 11 x 43 x 149 x 26 x 131 = 7201339860

Therefore, the lowest common multiple of 165,645,894,260,786 is 7201339860.

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.

165 x 645 x 894 x 260 x 786 = 19443617622000

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.

165 : 1, 3, 5, 11, 15, 33, 55, 165

645 : 1, 3, 5, 15, 43, 129, 215, 645

894 : 1, 2, 3, 6, 149, 298, 447, 894

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,645,894,260,786, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

645:3x 5x 43

894:2x 3x 149

260:2x 2x 5x 13

786:2x 3x 131

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

2x 2x 3x 3x 3x 5x 5 = 2700

Therefore, the value for common factors is 2700.

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 = 19443617622000/(1x2700)

LCM = 19443617622000/2700

LCM = 7201339860

Thus, we can understand that the LCM of 165,645,894,260,786 is 7201339860.
