The LCM of 765,725,990,102 is 2440350.
Find LCM of 765,725,990,102 with Prime Factorization
| 2 | 765, 725, 990, 102 |
| 3 | 765, 725, 495, 51 |
| 3 | 255, 725, 165, 17 |
| 5 | 85, 725, 55, 17 |
| 17 | 17, 145, 11, 17 |
| 1, 145, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 1 x 145 x 11 x 1 = 2440350
Therefore, the lowest common multiple of 765,725,990,102 is 2440350.
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.
765 x 725 x 990 x 102 = 56006032500
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
725 : 1, 5, 25, 29, 145, 725
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,725,990,102, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
725:5x 5x 29
990:2x 3x 3x 5x 11
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5x 17 = 22950
Therefore, the value for common factors is 22950.
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 = 56006032500/(1x22950)
LCM = 56006032500/22950
LCM = 2440350
Thus, we can understand that the LCM of 765,725,990,102 is 2440350.
