Find LCM of 104,403,672,385,920 with Prime Factorization
| 2 | 104, 403, 672, 385, 920 |
| 2 | 52, 403, 336, 385, 460 |
| 2 | 26, 403, 168, 385, 230 |
| 5 | 13, 403, 84, 385, 115 |
| 7 | 13, 403, 84, 77, 23 |
| 13 | 13, 403, 12, 11, 23 |
| 1, 31, 12, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 13 x 1 x 31 x 12 x 11 x 23 = 342582240
Therefore, the lowest common multiple of 104,403,672,385,920 is 342582240.
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.
104 x 403 x 672 x 385 x 920 = 9975994828800
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.
104 : 1, 2, 4, 8, 13, 26, 52, 104
403 : 1, 13, 31, 403
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
385 : 1, 5, 7, 11, 35, 55, 77, 385
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 104,403,672,385,920, is 1.
Now, the common factors can be found like this.
104:2x 2x 2x 13
403:13x 31
672:2x 2x 2x 2x 2x 3x 7
385:5x 7x 11
920:2x 2x 2x 5x 23
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 2x 2x 5x 7x 13 = 29120
Therefore, the value for common factors is 29120.
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 = 9975994828800/(1x29120)
LCM = 9975994828800/29120
LCM = 342582240
Thus, we can understand that the LCM of 104,403,672,385,920 is 342582240.
