Given numbers are 720,194,559,818,689

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

The LCM of 720,194,559,818,689 is 846282219120.

Find LCM of 720,194,559,818,689 with Prime Factorization

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

2 x 13 x 360 x 97 x 43 x 409 x 53 = 846282219120

Therefore, the lowest common multiple of 720,194,559,818,689 is 846282219120.

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 194 x 559 x 818 x 689 = 44006675394240

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

194 : 1, 2, 97, 194

559 : 1, 13, 43, 559

818 : 1, 2, 409, 818

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,194,559,818,689, is 1.

Now, the common factors can be found like this.

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

194:2x 97

559:13x 43

818:2x 409

689:13x 53

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 13 = 52

Therefore, the value for common factors is 52.

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 = 44006675394240/(1x52)

LCM = 44006675394240/52

LCM = 846282219120

Thus, we can understand that the LCM of 720,194,559,818,689 is 846282219120.
