Find LCM of 206,156,645,424,817 with Prime Factorization
| 2 | 206, 156, 645, 424, 817 |
| 2 | 103, 78, 645, 212, 817 |
| 3 | 103, 39, 645, 106, 817 |
| 43 | 103, 13, 215, 106, 817 |
| 103, 13, 5, 106, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 103 x 13 x 5 x 106 x 19 = 6957604680
Therefore, the lowest common multiple of 206,156,645,424,817 is 6957604680.
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.
206 x 156 x 645 x 424 x 817 = 7180248029760
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.
206 : 1, 2, 103, 206
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
645 : 1, 3, 5, 15, 43, 129, 215, 645
424 : 1, 2, 4, 8, 53, 106, 212, 424
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,156,645,424,817, is 1.
Now, the common factors can be found like this.
206:2x 103
156:2x 2x 3x 13
645:3x 5x 43
424:2x 2x 2x 53
817:19x 43
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 3x 43 = 1032
Therefore, the value for common factors is 1032.
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 = 7180248029760/(1x1032)
LCM = 7180248029760/1032
LCM = 6957604680
Thus, we can understand that the LCM of 206,156,645,424,817 is 6957604680.
