Find LCM of 808,625,720,930,685 with Prime Factorization
| 2 | 808, 625, 720, 930, 685 |
| 2 | 404, 625, 360, 465, 685 |
| 2 | 202, 625, 180, 465, 685 |
| 3 | 101, 625, 90, 465, 685 |
| 5 | 101, 625, 30, 155, 685 |
| 101, 125, 6, 31, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 101 x 125 x 6 x 31 x 137 = 38605230000
Therefore, the lowest common multiple of 808,625,720,930,685 is 38605230000.
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.
808 x 625 x 720 x 930 x 685 = 231631380000000
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
625 : 1, 5, 25, 125, 625
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
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,625,720,930,685, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
625:5x 5x 5x 5
720:2x 2x 2x 2x 3x 3x 5
930:2x 3x 5x 31
685:5x 137
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 5x 5x 5 = 6000
Therefore, the value for common factors is 6000.
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 = 231631380000000/(1x6000)
LCM = 231631380000000/6000
LCM = 38605230000
Thus, we can understand that the LCM of 808,625,720,930,685 is 38605230000.
