Given numbers are 634,326,640,163

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

The LCM of 634,326,640,163 is 33069440.

Find LCM of 634,326,640,163 with Prime Factorization

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

2 x 163 x 317 x 1 x 320 x 1 = 33069440

Therefore, the lowest common multiple of 634,326,640,163 is 33069440.

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.

634 x 326 x 640 x 163 = 21561274880

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.

634 : 1, 2, 317, 634

326 : 1, 2, 163, 326

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,326,640,163, is 1.

Now, the common factors can be found like this.

634:2x 317

326:2x 163

640:2x 2x 2x 2x 2x 2x 2x 5

163:163

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 163 = 652

Therefore, the value for common factors is 652.

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 = 21561274880/(1x652)

LCM = 21561274880/652

LCM = 33069440

Thus, we can understand that the LCM of 634,326,640,163 is 33069440.
