Given numbers are 406,488,671,669

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

The LCM of 406,488,671,669 is 729011976.

Find LCM of 406,488,671,669 with Prime Factorization

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

2 x 61 x 203 x 4 x 11 x 669 = 729011976

Therefore, the lowest common multiple of 406,488,671,669 is 729011976.

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 488 x 671 x 669 = 88939461072

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

488 : 1, 2, 4, 8, 61, 122, 244, 488

671 : 1, 11, 61, 671

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,488,671,669, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

488:2x 2x 2x 61

671:11x 61

669:3x 223

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

2x 61 = 122

Therefore, the value for common factors is 122.

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 = 88939461072/(1x122)

LCM = 88939461072/122

LCM = 729011976

Thus, we can understand that the LCM of 406,488,671,669 is 729011976.
