Given numbers are 638,803,489,376

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

The LCM of 638,803,489,376 is 4281640968.

Find LCM of 638,803,489,376 with Prime Factorization

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

2 x 11 x 29 x 73 x 489 x 188 = 4281640968

Therefore, the lowest common multiple of 638,803,489,376 is 4281640968.

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 803 x 489 x 376 = 94196101296

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

803 : 1, 11, 73, 803

489 : 1, 3, 163, 489

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,803,489,376, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

803:11x 73

489:3x 163

376:2x 2x 2x 47

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 94196101296/(1x22)

LCM = 94196101296/22

LCM = 4281640968

Thus, we can understand that the LCM of 638,803,489,376 is 4281640968.
