Find LCM of 920,765,816,706 with Prime Factorization
| 2 | 920, 765, 816, 706 |
| 2 | 460, 765, 408, 353 |
| 2 | 230, 765, 204, 353 |
| 3 | 115, 765, 102, 353 |
| 5 | 115, 255, 34, 353 |
| 17 | 23, 51, 34, 353 |
| 23, 3, 2, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 23 x 3 x 2 x 353 = 99376560
Therefore, the lowest common multiple of 920,765,816,706 is 99376560.
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.
920 x 765 x 816 x 706 = 405456364800
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
706 : 1, 2, 353, 706
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,765,816,706, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
765:3x 3x 5x 17
816:2x 2x 2x 2x 3x 17
706:2x 353
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 5x 17 = 4080
Therefore, the value for common factors is 4080.
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 = 405456364800/(1x4080)
LCM = 405456364800/4080
LCM = 99376560
Thus, we can understand that the LCM of 920,765,816,706 is 99376560.
