The LCM of 685,891,628,594 is 383290380.
Find LCM of 685,891,628,594 with Prime Factorization
| 2 | 685, 891, 628, 594 |
| 3 | 685, 891, 314, 297 |
| 3 | 685, 99, 314, 297 |
| 3 | 685, 33, 314, 99 |
| 11 | 685, 11, 314, 33 |
| 685, 1, 314, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 11 x 685 x 1 x 314 x 3 = 383290380
Therefore, the lowest common multiple of 685,891,628,594 is 383290380.
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.
685 x 891 x 628 x 594 = 227674485720
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.
685 : 1, 5, 137, 685
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
628 : 1, 2, 4, 157, 314, 628
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,891,628,594, is 1.
Now, the common factors can be found like this.
685:5x 137
891:3x 3x 3x 3x 11
628:2x 2x 157
594:2x 3x 3x 3x 11
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 11 = 594
Therefore, the value for common factors is 594.
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 = 227674485720/(1x594)
LCM = 227674485720/594
LCM = 383290380
Thus, we can understand that the LCM of 685,891,628,594 is 383290380.
