Given numbers are 638,750,443,792

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

The LCM of 638,750,443,792 is 1271853000.

Find LCM of 638,750,443,792 with Prime Factorization

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

2 x 3 x 11 x 29 x 125 x 443 x 12 = 1271853000

Therefore, the lowest common multiple of 638,750,443,792 is 1271853000.

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 750 x 443 x 792 = 167884596000

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

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

443 : 1, 443

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,750,443,792, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

750:2x 3x 5x 5x 5

443:443

792:2x 2x 2x 3x 3x 11

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 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 167884596000/(1x132)

LCM = 167884596000/132

LCM = 1271853000

Thus, we can understand that the LCM of 638,750,443,792 is 1271853000.
