Find LCM of 193,728,945,324 with Prime Factorization
| 2 | 193, 728, 945, 324 |
| 2 | 193, 364, 945, 162 |
| 3 | 193, 182, 945, 81 |
| 3 | 193, 182, 315, 27 |
| 3 | 193, 182, 105, 9 |
| 7 | 193, 182, 35, 3 |
| 193, 26, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 193 x 26 x 5 x 3 = 56904120
Therefore, the lowest common multiple of 193,728,945,324 is 56904120.
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.
193 x 728 x 945 x 324 = 43019514720
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.
193 : 1, 193
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,728,945,324, is 1.
Now, the common factors can be found like this.
193:193
728:2x 2x 2x 7x 13
945:3x 3x 3x 5x 7
324:2x 2x 3x 3x 3x 3
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 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 43019514720/(1x756)
LCM = 43019514720/756
LCM = 56904120
Thus, we can understand that the LCM of 193,728,945,324 is 56904120.
