Find LCM of 842,726,904,107,990 with Prime Factorization
2 | 842, 726, 904, 107, 990 |
3 | 421, 363, 452, 107, 495 |
11 | 421, 121, 452, 107, 165 |
421, 11, 452, 107, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 421 x 11 x 452 x 107 x 15 = 221733947160
Therefore, the lowest common multiple of 842,726,904,107,990 is 221733947160.
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.
842 x 726 x 904 x 107 x 990 = 58537762050240
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.
842 : 1, 2, 421, 842
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
904 : 1, 2, 4, 8, 113, 226, 452, 904
107 : 1, 107
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,726,904,107,990, is 1.
Now, the common factors can be found like this.
842:2x 421
726:2x 3x 11x 11
904:2x 2x 2x 113
107:107
990:2x 3x 3x 5x 11
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 11 = 264
Therefore, the value for common factors is 264.
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 = 58537762050240/(1x264)
LCM = 58537762050240/264
LCM = 221733947160
Thus, we can understand that the LCM of 842,726,904,107,990 is 221733947160.
