Find LCM of 724,891,765,918,816 with Prime Factorization
| 2 | 724, 891, 765, 918, 816 |
| 2 | 362, 891, 765, 459, 408 |
| 3 | 181, 891, 765, 459, 204 |
| 3 | 181, 297, 255, 153, 68 |
| 3 | 181, 99, 85, 51, 68 |
| 17 | 181, 33, 85, 17, 68 |
| 181, 33, 5, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 17 x 181 x 33 x 5 x 1 x 4 = 219328560
Therefore, the lowest common multiple of 724,891,765,918,816 is 219328560.
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.
724 x 891 x 765 x 918 x 816 = 369666882794880
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.
724 : 1, 2, 4, 181, 362, 724
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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 724,891,765,918,816, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
891:3x 3x 3x 3x 11
765:3x 3x 5x 17
918:2x 3x 3x 3x 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 2x 2x 3x 3x 3x 3x 3x 3x 17x 17 = 1685448
Therefore, the value for common factors is 1685448.
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 = 369666882794880/(1x1685448)
LCM = 369666882794880/1685448
LCM = 219328560
Thus, we can understand that the LCM of 724,891,765,918,816 is 219328560.
