Given numbers are 406,208,638,803

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

The LCM of 406,208,638,803 is 33905872.

Find LCM of 406,208,638,803 with Prime Factorization

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

2 x 11 x 29 x 7 x 104 x 1 x 73 = 33905872

Therefore, the lowest common multiple of 406,208,638,803 is 33905872.

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.

406 x 208 x 638 x 803 = 43263892672

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

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

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,208,638,803, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

208:2x 2x 2x 2x 13

638:2x 11x 29

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.

2x 2x 11x 29 = 1276

Therefore, the value for common factors is 1276.

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 = 43263892672/(1x1276)

LCM = 43263892672/1276

LCM = 33905872

Thus, we can understand that the LCM of 406,208,638,803 is 33905872.
