Find LCM of 819,331,553,993,390 with Prime Factorization
| 3 | 819, 331, 553, 993, 390 |
| 7 | 273, 331, 553, 331, 130 |
| 13 | 39, 331, 79, 331, 130 |
| 331 | 3, 331, 79, 331, 10 |
| 3, 1, 79, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 331 x 3 x 1 x 79 x 1 x 10 = 214160310
Therefore, the lowest common multiple of 819,331,553,993,390 is 214160310.
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.
819 x 331 x 553 x 993 x 390 = 58056504277590
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
331 : 1, 331
553 : 1, 7, 79, 553
993 : 1, 3, 331, 993
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,331,553,993,390, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
331:331
553:7x 79
993:3x 331
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 13x 331 = 271089
Therefore, the value for common factors is 271089.
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 = 58056504277590/(1x271089)
LCM = 58056504277590/271089
LCM = 214160310
Thus, we can understand that the LCM of 819,331,553,993,390 is 214160310.
