The LCM of 793,340,808,644,455 is 8768581640.
Find LCM of 793,340,808,644,455 with Prime Factorization
| 2 | 793, 340, 808, 644, 455 |
| 2 | 793, 170, 404, 322, 455 |
| 5 | 793, 85, 202, 161, 455 |
| 7 | 793, 17, 202, 161, 91 |
| 13 | 793, 17, 202, 23, 13 |
| 61, 17, 202, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 61 x 17 x 202 x 23 x 1 = 8768581640
Therefore, the lowest common multiple of 793,340,808,644,455 is 8768581640.
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.
793 x 340 x 808 x 644 x 455 = 63835274339200
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.
793 : 1, 13, 61, 793
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
808 : 1, 2, 4, 8, 101, 202, 404, 808
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,340,808,644,455, is 1.
Now, the common factors can be found like this.
793:13x 61
340:2x 2x 5x 17
808:2x 2x 2x 101
644:2x 2x 7x 23
455:5x 7x 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 5x 7x 13 = 7280
Therefore, the value for common factors is 7280.
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 = 63835274339200/(1x7280)
LCM = 63835274339200/7280
LCM = 8768581640
Thus, we can understand that the LCM of 793,340,808,644,455 is 8768581640.
