The LCM of 684,855,625,755 is 64552500.
Find LCM of 684,855,625,755 with Prime Factorization
| 3 | 684, 855, 625, 755 |
| 3 | 228, 285, 625, 755 |
| 5 | 76, 95, 625, 755 |
| 19 | 76, 19, 125, 151 |
| 4, 1, 125, 151 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 4 x 1 x 125 x 151 = 64552500
Therefore, the lowest common multiple of 684,855,625,755 is 64552500.
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.
684 x 855 x 625 x 755 = 275961937500
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
625 : 1, 5, 25, 125, 625
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,855,625,755, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
855:3x 3x 5x 19
625:5x 5x 5x 5
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 19 = 4275
Therefore, the value for common factors is 4275.
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 = 275961937500/(1x4275)
LCM = 275961937500/4275
LCM = 64552500
Thus, we can understand that the LCM of 684,855,625,755 is 64552500.
