Given numbers are 726,547,720,406

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

The LCM of 726,547,720,406 is 9673891920.

Find LCM of 726,547,720,406 with Prime Factorization

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

2 x 3 x 121 x 547 x 120 x 203 = 9673891920

Therefore, the lowest common multiple of 726,547,720,406 is 9673891920.

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 547 x 720 x 406 = 116086703040

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

547 : 1, 547

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,547,720,406, is 1.

Now, the common factors can be found like this.

726:2x 3x 11x 11

547:547

720:2x 2x 2x 2x 3x 3x 5

406:2x 7x 29

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 3 = 12

Therefore, the value for common factors is 12.

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 = 116086703040/(1x12)

LCM = 116086703040/12

LCM = 9673891920

Thus, we can understand that the LCM of 726,547,720,406 is 9673891920.
