| 5 | 185, 31, 10, 229, 691 |
| 37, 31, 2, 229, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 37 x 31 x 2 x 229 x 691 = 174240127680
Therefore, the lowest common multiple of 185,992,960,687,691 is 174240127680.
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.
185 x 992 x 960 x 687 x 691 = 83635261286400
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.
185 : 1, 5, 37, 185
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
687 : 1, 3, 229, 687
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,992,960,687,691, is 1.
Now, the common factors can be found like this.
185:5x 37
992:2x 2x 2x 2x 2x 31
960:2x 2x 2x 2x 2x 2x 3x 5
687:3x 229
691:691
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 5 = 480
Therefore, the value for common factors is 480.
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 = 83635261286400/(1x480)
LCM = 83635261286400/480
LCM = 174240127680
Thus, we can understand that the LCM of 185,992,960,687,691 is 174240127680.
