Find LCM of 976,865,957,724,990 with Prime Factorization
| 2 | 976, 865, 957, 724, 990 |
| 2 | 488, 865, 957, 362, 495 |
| 3 | 244, 865, 957, 181, 495 |
| 5 | 244, 865, 319, 181, 165 |
| 11 | 244, 173, 319, 181, 33 |
| 244, 173, 29, 181, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 244 x 173 x 29 x 181 x 3 = 438710160240
Therefore, the lowest common multiple of 976,865,957,724,990 is 438710160240.
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.
976 x 865 x 957 x 724 x 990 = 579097411516800
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
865 : 1, 5, 173, 865
957 : 1, 3, 11, 29, 33, 87, 319, 957
724 : 1, 2, 4, 181, 362, 724
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 976,865,957,724,990, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
865:5x 173
957:3x 11x 29
724:2x 2x 181
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 579097411516800/(1x1320)
LCM = 579097411516800/1320
LCM = 438710160240
Thus, we can understand that the LCM of 976,865,957,724,990 is 438710160240.
