Find LCM of 810,560,923,630,728 with Prime Factorization
| 2 | 810, 560, 923, 630, 728 |
| 2 | 405, 280, 923, 315, 364 |
| 2 | 405, 140, 923, 315, 182 |
| 3 | 405, 70, 923, 315, 91 |
| 3 | 135, 70, 923, 105, 91 |
| 5 | 45, 70, 923, 35, 91 |
| 7 | 9, 14, 923, 7, 91 |
| 13 | 9, 2, 923, 1, 13 |
| 9, 2, 71, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 7 x 13 x 9 x 2 x 71 x 1 x 1 = 41867280
Therefore, the lowest common multiple of 810,560,923,630,728 is 41867280.
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.
810 x 560 x 923 x 630 x 728 = 192020092992000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
923 : 1, 13, 71, 923
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,560,923,630,728, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
560:2x 2x 2x 2x 5x 7
923:13x 71
630:2x 3x 3x 5x 7
728:2x 2x 2x 7x 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 3x 3x 5x 5x 7x 7x 13 = 4586400
Therefore, the value for common factors is 4586400.
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 = 192020092992000/(1x4586400)
LCM = 192020092992000/4586400
LCM = 41867280
Thus, we can understand that the LCM of 810,560,923,630,728 is 41867280.
