Given numbers are 406,217,580,928,991

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

The LCM of 406,217,580,928,991 is 997818080.

Find LCM of 406,217,580,928,991 with Prime Factorization

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

2 x 2 x 7 x 29 x 1 x 31 x 5 x 8 x 991 = 997818080

Therefore, the lowest common multiple of 406,217,580,928,991 is 997818080.

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 217 x 580 x 928 x 991 = 46993240295680

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

217 : 1, 7, 31, 217

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,217,580,928,991, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

217:7x 31

580:2x 2x 5x 29

928:2x 2x 2x 2x 2x 29

991:991

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 2x 7x 29x 29 = 47096

Therefore, the value for common factors is 47096.

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 = 46993240295680/(1x47096)

LCM = 46993240295680/47096

LCM = 997818080

Thus, we can understand that the LCM of 406,217,580,928,991 is 997818080.
