Find LCM of 123,108,943,548,915 with Prime Factorization
| 2 | 123, 108, 943, 548, 915 |
| 2 | 123, 54, 943, 274, 915 |
| 3 | 123, 27, 943, 137, 915 |
| 41 | 41, 9, 943, 137, 305 |
| 1, 9, 23, 137, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 1 x 9 x 23 x 137 x 305 = 4255551540
Therefore, the lowest common multiple of 123,108,943,548,915 is 4255551540.
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.
123 x 108 x 943 x 548 x 915 = 6281194073040
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.
123 : 1, 3, 41, 123
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
943 : 1, 23, 41, 943
548 : 1, 2, 4, 137, 274, 548
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,108,943,548,915, is 1.
Now, the common factors can be found like this.
123:3x 41
108:2x 2x 3x 3x 3
943:23x 41
548:2x 2x 137
915:3x 5x 61
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 3x 3x 41 = 1476
Therefore, the value for common factors is 1476.
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 = 6281194073040/(1x1476)
LCM = 6281194073040/1476
LCM = 4255551540
Thus, we can understand that the LCM of 123,108,943,548,915 is 4255551540.
