Given numbers are 720,523,747,805,515

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

The LCM of 720,523,747,805,515 is 518293041840.

Find LCM of 720,523,747,805,515 with Prime Factorization

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

3 x 3 x 5 x 16 x 523 x 83 x 161 x 103 = 518293041840

Therefore, the lowest common multiple of 720,523,747,805,515 is 518293041840.

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 523 x 747 x 805 x 515 = 116615934414000

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

523 : 1, 523

747 : 1, 3, 9, 83, 249, 747

805 : 1, 5, 7, 23, 35, 115, 161, 805

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,523,747,805,515, is 1.

Now, the common factors can be found like this.

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

523:523

747:3x 3x 83

805:5x 7x 23

515:5x 103

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 5x 5 = 225

Therefore, the value for common factors is 225.

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 = 116615934414000/(1x225)

LCM = 116615934414000/225

LCM = 518293041840

Thus, we can understand that the LCM of 720,523,747,805,515 is 518293041840.
