Given numbers are 409,777,621,581

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

The LCM of 409,777,621,581 is 5460001533.

Find LCM of 409,777,621,581 with Prime Factorization

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

3 x 7 x 409 x 37 x 207 x 83 = 5460001533

Therefore, the lowest common multiple of 409,777,621,581 is 5460001533.

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.

409 x 777 x 621 x 581 = 114660032193

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.

409 : 1, 409

777 : 1, 3, 7, 21, 37, 111, 259, 777

621 : 1, 3, 9, 23, 27, 69, 207, 621

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,777,621,581, is 1.

Now, the common factors can be found like this.

409:409

777:3x 7x 37

621:3x 3x 3x 23

581:7x 83

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 114660032193/(1x21)

LCM = 114660032193/21

LCM = 5460001533

Thus, we can understand that the LCM of 409,777,621,581 is 5460001533.
