Given numbers are 638,352,320,326

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

The LCM of 638,352,320,326 is 16639040.

Find LCM of 638,352,320,326 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 11 x 29 x 1 x 10 x 163 = 16639040

Therefore, the lowest common multiple of 638,352,320,326 is 16639040.

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.

638 x 352 x 320 x 326 = 23427768320

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

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

326 : 1, 2, 163, 326

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,352,320,326, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

352:2x 2x 2x 2x 2x 11

320:2x 2x 2x 2x 2x 2x 5

326:2x 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 2x 2x 2x 2x 11 = 704

Therefore, the value for common factors is 704.

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 = 23427768320/(2x704)

LCM = 23427768320/1408

LCM = 16639040

Thus, we can understand that the LCM of 638,352,320,326 is 16639040.
