Given numbers are 638,823,472,326

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

The LCM of 638,823,472,326 is 20198546632.

Find LCM of 638,823,472,326 with Prime Factorization

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

2 x 319 x 823 x 236 x 163 = 20198546632

Therefore, the lowest common multiple of 638,823,472,326 is 20198546632.

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 823 x 472 x 326 = 80794186528

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

823 : 1, 823

472 : 1, 2, 4, 8, 59, 118, 236, 472

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,823,472,326, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

823:823

472:2x 2x 2x 59

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 2 = 4

Therefore, the value for common factors is 4.

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 = 80794186528/(1x4)

LCM = 80794186528/4

LCM = 20198546632

Thus, we can understand that the LCM of 638,823,472,326 is 20198546632.
