Find LCM of 192,689,345,720 with Prime Factorization
| 2 | 192, 689, 345, 720 |
| 2 | 96, 689, 345, 360 |
| 2 | 48, 689, 345, 180 |
| 2 | 24, 689, 345, 90 |
| 3 | 12, 689, 345, 45 |
| 5 | 4, 689, 115, 15 |
| 4, 689, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 4 x 689 x 23 x 3 = 45639360
Therefore, the lowest common multiple of 192,689,345,720 is 45639360.
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.
192 x 689 x 345 x 720 = 32860339200
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
689 : 1, 13, 53, 689
345 : 1, 3, 5, 15, 23, 69, 115, 345
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,689,345,720, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
689:13x 53
345:3x 5x 23
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 32860339200/(1x720)
LCM = 32860339200/720
LCM = 45639360
Thus, we can understand that the LCM of 192,689,345,720 is 45639360.
