| 11 | 1, 299, 11, 46, 297 |
| 23 | 1, 299, 1, 46, 27 |
| 1, 13, 1, 2, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 11 x 23 x 1 x 13 x 1 x 2 x 27 = 149189040
Therefore, the lowest common multiple of 280,897,385,368,891 is 149189040.
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.
280 x 897 x 385 x 368 x 891 = 31705654780800
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
897 : 1, 3, 13, 23, 39, 69, 299, 897
385 : 1, 5, 7, 11, 35, 55, 77, 385
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,897,385,368,891, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
897:3x 13x 23
385:5x 7x 11
368:2x 2x 2x 2x 23
891:3x 3x 3x 3x 11
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 3x 5x 7x 11x 23 = 212520
Therefore, the value for common factors is 212520.
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 = 31705654780800/(1x212520)
LCM = 31705654780800/212520
LCM = 149189040
Thus, we can understand that the LCM of 280,897,385,368,891 is 149189040.
