Given numbers are 726,921,454,810

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

The LCM of 726,921,454,810 is 6830218890.

Find LCM of 726,921,454,810 with Prime Factorization

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

2 x 3 x 121 x 307 x 227 x 135 = 6830218890

Therefore, the lowest common multiple of 726,921,454,810 is 6830218890.

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.

726 x 921 x 454 x 810 = 245887880040

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.

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

921 : 1, 3, 307, 921

454 : 1, 2, 227, 454

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,921,454,810, is 1.

Now, the common factors can be found like this.

726:2x 3x 11x 11

921:3x 307

454:2x 227

810:2x 3x 3x 3x 3x 5

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 245887880040/(1x36)

LCM = 245887880040/36

LCM = 6830218890

Thus, we can understand that the LCM of 726,921,454,810 is 6830218890.
