Find LCM of 280,816,802,936,845 with Prime Factorization
| 2 | 280, 816, 802, 936, 845 |
| 2 | 140, 408, 401, 468, 845 |
| 2 | 70, 204, 401, 234, 845 |
| 3 | 35, 102, 401, 117, 845 |
| 5 | 35, 34, 401, 39, 845 |
| 13 | 7, 34, 401, 39, 169 |
| 7, 34, 401, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 7 x 34 x 401 x 3 x 13 = 5806447920
Therefore, the lowest common multiple of 280,816,802,936,845 is 5806447920.
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 816 x 802 x 936 x 845 = 144928940083200
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
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
802 : 1, 2, 401, 802
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,816,802,936,845, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
816:2x 2x 2x 2x 3x 17
802:2x 401
936:2x 2x 2x 3x 3x 13
845:5x 13x 13
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 2x 2x 3x 5x 13 = 24960
Therefore, the value for common factors is 24960.
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 = 144928940083200/(1x24960)
LCM = 144928940083200/24960
LCM = 5806447920
Thus, we can understand that the LCM of 280,816,802,936,845 is 5806447920.
