Given numbers are 165,163,408,406,969

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

The LCM of 165,163,408,406,969 is 14107826040.

Find LCM of 165,163,408,406,969 with Prime Factorization

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

2 x 3 x 17 x 55 x 163 x 4 x 203 x 19 = 14107826040

Therefore, the lowest common multiple of 165,163,408,406,969 is 14107826040.

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 163 x 408 x 406 x 969 = 4316994768240

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

163 : 1, 163

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

406 : 1, 2, 7, 14, 29, 58, 203, 406

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,163,408,406,969, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

163:163

408:2x 2x 2x 3x 17

406:2x 7x 29

969:3x 17x 19

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

2x 3x 3x 17 = 306

Therefore, the value for common factors is 306.

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 = 4316994768240/(1x306)

LCM = 4316994768240/306

LCM = 14107826040

Thus, we can understand that the LCM of 165,163,408,406,969 is 14107826040.
