The LCM of 315,255,442,647,667 is 60084567270.
Find LCM of 315,255,442,647,667 with Prime Factorization
| 3 | 315, 255, 442, 647, 667 |
| 5 | 105, 85, 442, 647, 667 |
| 17 | 21, 17, 442, 647, 667 |
| 21, 1, 26, 647, 667 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 21 x 1 x 26 x 647 x 667 = 60084567270
Therefore, the lowest common multiple of 315,255,442,647,667 is 60084567270.
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.
315 x 255 x 442 x 647 x 667 = 15321564653850
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
255 : 1, 3, 5, 15, 17, 51, 85, 255
442 : 1, 2, 13, 17, 26, 34, 221, 442
647 : 1, 647
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,255,442,647,667, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
255:3x 5x 17
442:2x 13x 17
647:647
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17 = 255
Therefore, the value for common factors is 255.
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 = 15321564653850/(1x255)
LCM = 15321564653850/255
LCM = 60084567270
Thus, we can understand that the LCM of 315,255,442,647,667 is 60084567270.
