Find LCM of 720,825,108,916,936 with Prime Factorization
| 2 | 720, 825, 108, 916, 936 |
| 2 | 360, 825, 54, 458, 468 |
| 2 | 180, 825, 27, 229, 234 |
| 3 | 90, 825, 27, 229, 117 |
| 3 | 30, 275, 9, 229, 39 |
| 5 | 10, 275, 3, 229, 13 |
| 2, 55, 3, 229, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 2 x 55 x 3 x 229 x 13 = 353667600
Therefore, the lowest common multiple of 720,825,108,916,936 is 353667600.
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.
720 x 825 x 108 x 916 x 936 = 55002385152000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
916 : 1, 2, 4, 229, 458, 916
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,825,108,916,936, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
825:3x 5x 5x 11
108:2x 2x 3x 3x 3
916:2x 2x 229
936:2x 2x 2x 3x 3x 13
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 2x 3x 3x 3x 3x 3x 5 = 155520
Therefore, the value for common factors is 155520.
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 = 55002385152000/(1x155520)
LCM = 55002385152000/155520
LCM = 353667600
Thus, we can understand that the LCM of 720,825,108,916,936 is 353667600.
