Find LCM of 819,773,585,315 with Prime Factorization
| 3 | 819, 773, 585, 315 |
| 3 | 273, 773, 195, 105 |
| 5 | 91, 773, 65, 35 |
| 7 | 91, 773, 13, 7 |
| 13 | 13, 773, 13, 1 |
| 1, 773, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 13 x 1 x 773 x 1 x 1 = 3165435
Therefore, the lowest common multiple of 819,773,585,315 is 3165435.
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.
819 x 773 x 585 x 315 = 116662106925
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
773 : 1, 773
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,773,585,315, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
773:773
585:3x 3x 5x 13
315:3x 3x 5x 7
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 3x 3x 5x 7x 13 = 36855
Therefore, the value for common factors is 36855.
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 = 116662106925/(1x36855)
LCM = 116662106925/36855
LCM = 3165435
Thus, we can understand that the LCM of 819,773,585,315 is 3165435.
