Find LCM of 646,819,491,247,792 with Prime Factorization
| 2 | 646, 819, 491, 247, 792 |
| 3 | 323, 819, 491, 247, 396 |
| 3 | 323, 273, 491, 247, 132 |
| 13 | 323, 91, 491, 247, 44 |
| 19 | 323, 7, 491, 19, 44 |
| 17, 7, 491, 1, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 19 x 17 x 7 x 491 x 1 x 44 = 11430114696
Therefore, the lowest common multiple of 646,819,491,247,792 is 11430114696.
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.
646 x 819 x 491 x 247 x 792 = 50818289938416
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
491 : 1, 491
247 : 1, 13, 19, 247
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,819,491,247,792, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
819:3x 3x 7x 13
491:491
247:13x 19
792:2x 2x 2x 3x 3x 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 3x 3x 13x 19 = 4446
Therefore, the value for common factors is 4446.
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 = 50818289938416/(1x4446)
LCM = 50818289938416/4446
LCM = 11430114696
Thus, we can understand that the LCM of 646,819,491,247,792 is 11430114696.
