Find LCM of 816,615,822,136 with Prime Factorization
| 2 | 816, 615, 822, 136 |
| 2 | 408, 615, 411, 68 |
| 2 | 204, 615, 411, 34 |
| 3 | 102, 615, 411, 17 |
| 17 | 34, 205, 137, 17 |
| 2, 205, 137, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 2 x 205 x 137 x 1 = 22917360
Therefore, the lowest common multiple of 816,615,822,136 is 22917360.
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.
816 x 615 x 822 x 136 = 56101697280
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
615 : 1, 3, 5, 15, 41, 123, 205, 615
822 : 1, 2, 3, 6, 137, 274, 411, 822
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,615,822,136, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
615:3x 5x 41
822:2x 3x 137
136:2x 2x 2x 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 3x 3x 17 = 2448
Therefore, the value for common factors is 2448.
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 = 56101697280/(1x2448)
LCM = 56101697280/2448
LCM = 22917360
Thus, we can understand that the LCM of 816,615,822,136 is 22917360.
