Find LCM of 796,800,968,960,638 with Prime Factorization
| 2 | 796, 800, 968, 960, 638 |
| 2 | 398, 400, 484, 480, 319 |
| 2 | 199, 200, 242, 240, 319 |
| 2 | 199, 100, 121, 120, 319 |
| 2 | 199, 50, 121, 60, 319 |
| 5 | 199, 25, 121, 30, 319 |
| 11 | 199, 5, 121, 6, 319 |
| 199, 5, 11, 6, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 11 x 199 x 5 x 11 x 6 x 29 = 3351796800
Therefore, the lowest common multiple of 796,800,968,960,638 is 3351796800.
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.
796 x 800 x 968 x 960 x 638 = 377546391552000
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.
796 : 1, 2, 4, 199, 398, 796
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 796,800,968,960,638, is 2.
Now, the common factors can be found like this.
796:2x 2x 199
800:2x 2x 2x 2x 2x 5x 5
968:2x 2x 2x 11x 11
960:2x 2x 2x 2x 2x 2x 3x 5
638:2x 11x 29
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 2x 2x 2x 2x 2x 2x 2x 5x 11 = 56320
Therefore, the value for common factors is 56320.
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 = 377546391552000/(2x56320)
LCM = 377546391552000/112640
LCM = 3351796800
Thus, we can understand that the LCM of 796,800,968,960,638 is 3351796800.
