Given numbers are 404,726,921,409

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

The LCM of 404,726,921,409 is 18414065076.

Find LCM of 404,726,921,409 with Prime Factorization

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

2 x 3 x 202 x 121 x 307 x 409 = 18414065076

Therefore, the lowest common multiple of 404,726,921,409 is 18414065076.

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.

404 x 726 x 921 x 409 = 110484390456

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.

404 : 1, 2, 4, 101, 202, 404

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

921 : 1, 3, 307, 921

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,726,921,409, is 1.

Now, the common factors can be found like this.

404:2x 2x 101

726:2x 3x 11x 11

921:3x 307

409:409

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 110484390456/(1x6)

LCM = 110484390456/6

LCM = 18414065076

Thus, we can understand that the LCM of 404,726,921,409 is 18414065076.
