Given numbers are 638,493,807,803

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

The LCM of 638,493,807,803 is 638948706.

Find LCM of 638,493,807,803 with Prime Factorization

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

11 x 29 x 2 x 17 x 807 x 73 = 638948706

Therefore, the lowest common multiple of 638,493,807,803 is 638948706.

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 493 x 807 x 803 = 203824637214

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

493 : 1, 17, 29, 493

807 : 1, 3, 269, 807

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,493,807,803, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

493:17x 29

807:3x 269

803:11x 73

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

11x 29 = 319

Therefore, the value for common factors is 319.

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 = 203824637214/(1x319)

LCM = 203824637214/319

LCM = 638948706

Thus, we can understand that the LCM of 638,493,807,803 is 638948706.
