Given numbers are 720,817,273,609,917

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

The LCM of 720,817,273,609,917 is 203359862160.

Find LCM of 720,817,273,609,917 with Prime Factorization

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

3 x 7 x 240 x 817 x 13 x 29 x 131 = 203359862160

Therefore, the lowest common multiple of 720,817,273,609,917 is 203359862160.

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.

720 x 817 x 273 x 609 x 917 = 89681699212560

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.

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

817 : 1, 19, 43, 817

273 : 1, 3, 7, 13, 21, 39, 91, 273

609 : 1, 3, 7, 21, 29, 87, 203, 609

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,817,273,609,917, is 1.

Now, the common factors can be found like this.

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

817:19x 43

273:3x 7x 13

609:3x 7x 29

917:7x 131

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

3x 3x 7x 7 = 441

Therefore, the value for common factors is 441.

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 = 89681699212560/(1x441)

LCM = 89681699212560/441

LCM = 203359862160

Thus, we can understand that the LCM of 720,817,273,609,917 is 203359862160.
