The LCM of 387,560,993,868,963 is 237942739440.
Find LCM of 387,560,993,868,963 with Prime Factorization
| 2 | 387, 560, 993, 868, 963 |
| 2 | 387, 280, 993, 434, 963 |
| 3 | 387, 140, 993, 217, 963 |
| 3 | 129, 140, 331, 217, 321 |
| 7 | 43, 140, 331, 217, 107 |
| 43, 20, 331, 31, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 43 x 20 x 331 x 31 x 107 = 237942739440
Therefore, the lowest common multiple of 387,560,993,868,963 is 237942739440.
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.
387 x 560 x 993 x 868 x 963 = 179884711016640
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.
387 : 1, 3, 9, 43, 129, 387
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
993 : 1, 3, 331, 993
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
963 : 1, 3, 9, 107, 321, 963
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,560,993,868,963, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
560:2x 2x 2x 2x 5x 7
993:3x 331
868:2x 2x 7x 31
963:3x 3x 107
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 179884711016640/(1x756)
LCM = 179884711016640/756
LCM = 237942739440
Thus, we can understand that the LCM of 387,560,993,868,963 is 237942739440.
