The LCM of 897,286,713,992 is 9788064.
Find LCM of 897,286,713,992 with Prime Factorization
| 2 | 897, 286, 713, 992 |
| 13 | 897, 143, 713, 496 |
| 23 | 69, 11, 713, 496 |
| 31 | 3, 11, 31, 496 |
| 3, 11, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 23 x 31 x 3 x 11 x 1 x 16 = 9788064
Therefore, the lowest common multiple of 897,286,713,992 is 9788064.
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.
897 x 286 x 713 x 992 = 181451130432
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
286 : 1, 2, 11, 13, 22, 26, 143, 286
713 : 1, 23, 31, 713
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,286,713,992, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
286:2x 11x 13
713:23x 31
992:2x 2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 23x 31 = 18538
Therefore, the value for common factors is 18538.
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 = 181451130432/(1x18538)
LCM = 181451130432/18538
LCM = 9788064
Thus, we can understand that the LCM of 897,286,713,992 is 9788064.
