Find LCM of 218,216,870,861,816 with Prime Factorization
| 2 | 218, 216, 870, 861, 816 |
| 2 | 109, 108, 435, 861, 408 |
| 2 | 109, 54, 435, 861, 204 |
| 3 | 109, 27, 435, 861, 102 |
| 109, 9, 145, 287, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 109 x 9 x 145 x 287 x 34 = 33312641040
Therefore, the lowest common multiple of 218,216,870,861,816 is 33312641040.
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.
218 x 216 x 870 x 861 x 816 = 28782121858560
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.
218 : 1, 2, 109, 218
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
861 : 1, 3, 7, 21, 41, 123, 287, 861
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 218,216,870,861,816, is 1.
Now, the common factors can be found like this.
218:2x 109
216:2x 2x 2x 3x 3x 3
870:2x 3x 5x 29
861:3x 7x 41
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 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 28782121858560/(1x864)
LCM = 28782121858560/864
LCM = 33312641040
Thus, we can understand that the LCM of 218,216,870,861,816 is 33312641040.
