Find LCM of 765,206,423,595,816 with Prime Factorization
| 2 | 765, 206, 423, 595, 816 |
| 3 | 765, 103, 423, 595, 408 |
| 3 | 255, 103, 141, 595, 136 |
| 5 | 85, 103, 47, 595, 136 |
| 17 | 17, 103, 47, 119, 136 |
| 1, 103, 47, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 1 x 103 x 47 x 7 x 8 = 414776880
Therefore, the lowest common multiple of 765,206,423,595,816 is 414776880.
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 206 x 423 x 595 x 816 = 32365039946400
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
206 : 1, 2, 103, 206
423 : 1, 3, 9, 47, 141, 423
595 : 1, 5, 7, 17, 35, 85, 119, 595
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,206,423,595,816, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
206:2x 103
423:3x 3x 47
595:5x 7x 17
816:2x 2x 2x 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 17x 17 = 78030
Therefore, the value for common factors is 78030.
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 = 32365039946400/(1x78030)
LCM = 32365039946400/78030
LCM = 414776880
Thus, we can understand that the LCM of 765,206,423,595,816 is 414776880.
