| 11 | 197, 187, 77, 97, 10 |
| 197, 17, 7, 97, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 11 x 197 x 17 x 7 x 97 x 10 = 18009850320
Therefore, the lowest common multiple of 788,187,616,873,720 is 18009850320.
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.
788 x 187 x 616 x 873 x 720 = 57055205813760
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.
788 : 1, 2, 4, 197, 394, 788
187 : 1, 11, 17, 187
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
873 : 1, 3, 9, 97, 291, 873
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,187,616,873,720, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
187:11x 17
616:2x 2x 2x 7x 11
873:3x 3x 97
720:2x 2x 2x 2x 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 2x 2x 2x 3x 3x 11 = 3168
Therefore, the value for common factors is 3168.
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 = 57055205813760/(1x3168)
LCM = 57055205813760/3168
LCM = 18009850320
Thus, we can understand that the LCM of 788,187,616,873,720 is 18009850320.
