The LCM of 417,442,857,861,442 is 45333687126.
Find LCM of 417,442,857,861,442 with Prime Factorization
| 2 | 417, 442, 857, 861, 442 |
| 3 | 417, 221, 857, 861, 221 |
| 13 | 139, 221, 857, 287, 221 |
| 17 | 139, 17, 857, 287, 17 |
| 139, 1, 857, 287, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 139 x 1 x 857 x 287 x 1 = 45333687126
Therefore, the lowest common multiple of 417,442,857,861,442 is 45333687126.
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.
417 x 442 x 857 x 861 x 442 = 60112469129076
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.
417 : 1, 3, 139, 417
442 : 1, 2, 13, 17, 26, 34, 221, 442
857 : 1, 857
861 : 1, 3, 7, 21, 41, 123, 287, 861
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,442,857,861,442, is 1.
Now, the common factors can be found like this.
417:3x 139
442:2x 13x 17
857:857
861:3x 7x 41
442:2x 13x 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 3x 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 60112469129076/(1x1326)
LCM = 60112469129076/1326
LCM = 45333687126
Thus, we can understand that the LCM of 417,442,857,861,442 is 45333687126.
