Given numbers are 163,664,163,165

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

The LCM of 163,664,163,165 is 17858280.

Find LCM of 163,664,163,165 with Prime Factorization

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

163 x 1 x 664 x 1 x 165 = 17858280

Therefore, the lowest common multiple of 163,664,163,165 is 17858280.

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 664 x 163 x 165 = 2910899640

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

163 : 1, 163

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,664,163,165, is 1.

Now, the common factors can be found like this.

163:163

664:2x 2x 2x 83

163:163

165:3x 5x 11

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

163 = 163

Therefore, the value for common factors is 163.

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 = 2910899640/(1x163)

LCM = 2910899640/163

LCM = 17858280

Thus, we can understand that the LCM of 163,664,163,165 is 17858280.
