Find LCM of 784,990,568,961,117 with Prime Factorization
| 2 | 784, 990, 568, 961, 117 |
| 2 | 392, 495, 284, 961, 117 |
| 2 | 196, 495, 142, 961, 117 |
| 3 | 98, 495, 71, 961, 117 |
| 3 | 98, 165, 71, 961, 39 |
| 98, 55, 71, 961, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 98 x 55 x 71 x 961 x 13 = 344228124240
Therefore, the lowest common multiple of 784,990,568,961,117 is 344228124240.
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.
784 x 990 x 568 x 961 x 117 = 49568849890560
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
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
568 : 1, 2, 4, 8, 71, 142, 284, 568
961 : 1, 31, 961
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,990,568,961,117, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
990:2x 3x 3x 5x 11
568:2x 2x 2x 71
961:31x 31
117:3x 3x 13
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 49568849890560/(1x144)
LCM = 49568849890560/144
LCM = 344228124240
Thus, we can understand that the LCM of 784,990,568,961,117 is 344228124240.
