Find LCM of 459,280,868,816 with Prime Factorization
| 2 | 459, 280, 868, 816 |
| 2 | 459, 140, 434, 408 |
| 2 | 459, 70, 217, 204 |
| 3 | 459, 35, 217, 102 |
| 7 | 153, 35, 217, 34 |
| 17 | 153, 5, 31, 34 |
| 9, 5, 31, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 17 x 9 x 5 x 31 x 2 = 7968240
Therefore, the lowest common multiple of 459,280,868,816 is 7968240.
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.
459 x 280 x 868 x 816 = 91029173760
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,280,868,816, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
280:2x 2x 2x 5x 7
868:2x 2x 7x 31
816:2x 2x 2x 2x 3x 17
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 7x 17 = 11424
Therefore, the value for common factors is 11424.
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 = 91029173760/(1x11424)
LCM = 91029173760/11424
LCM = 7968240
Thus, we can understand that the LCM of 459,280,868,816 is 7968240.
