Find LCM of 782,442,393,897 with Prime Factorization
| 2 | 782, 442, 393, 897 |
| 3 | 391, 221, 393, 897 |
| 13 | 391, 221, 131, 299 |
| 17 | 391, 17, 131, 23 |
| 23 | 23, 1, 131, 23 |
| 1, 1, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 23 x 1 x 1 x 131 x 1 = 3995238
Therefore, the lowest common multiple of 782,442,393,897 is 3995238.
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.
782 x 442 x 393 x 897 = 121846768524
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
442 : 1, 2, 13, 17, 26, 34, 221, 442
393 : 1, 3, 131, 393
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,442,393,897, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
442:2x 13x 17
393:3x 131
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 17x 23 = 30498
Therefore, the value for common factors is 30498.
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 = 121846768524/(1x30498)
LCM = 121846768524/30498
LCM = 3995238
Thus, we can understand that the LCM of 782,442,393,897 is 3995238.
