Find LCM of 864,117,989,897 with Prime Factorization
| 3 | 864, 117, 989, 897 |
| 3 | 288, 39, 989, 299 |
| 13 | 96, 13, 989, 299 |
| 23 | 96, 1, 989, 23 |
| 96, 1, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 23 x 96 x 1 x 43 x 1 = 11108448
Therefore, the lowest common multiple of 864,117,989,897 is 11108448.
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.
864 x 117 x 989 x 897 = 89678500704
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
117 : 1, 3, 9, 13, 39, 117
989 : 1, 23, 43, 989
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,117,989,897, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
117:3x 3x 13
989:23x 43
897:3x 13x 23
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 3x 13x 23 = 8073
Therefore, the value for common factors is 8073.
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 = 89678500704/(1x8073)
LCM = 89678500704/8073
LCM = 11108448
Thus, we can understand that the LCM of 864,117,989,897 is 11108448.
