Find LCM of 390,323,847,505,884 with Prime Factorization
| 2 | 390, 323, 847, 505, 884 |
| 5 | 195, 323, 847, 505, 442 |
| 13 | 39, 323, 847, 101, 442 |
| 17 | 3, 323, 847, 101, 34 |
| 3, 19, 847, 101, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 17 x 3 x 19 x 847 x 101 x 2 = 21552711180
Therefore, the lowest common multiple of 390,323,847,505,884 is 21552711180.
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.
390 x 323 x 847 x 505 x 884 = 47631491707800
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
323 : 1, 17, 19, 323
847 : 1, 7, 11, 77, 121, 847
505 : 1, 5, 101, 505
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,323,847,505,884, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
323:17x 19
847:7x 11x 11
505:5x 101
884:2x 2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 17 = 2210
Therefore, the value for common factors is 2210.
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 = 47631491707800/(1x2210)
LCM = 47631491707800/2210
LCM = 21552711180
Thus, we can understand that the LCM of 390,323,847,505,884 is 21552711180.
