Find LCM of 667,814,819,561,729 with Prime Factorization
| 3 | 667, 814, 819, 561, 729 |
| 3 | 667, 814, 273, 187, 243 |
| 11 | 667, 814, 91, 187, 81 |
| 667, 74, 91, 17, 81 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 667 x 74 x 91 x 17 x 81 = 612305387694
Therefore, the lowest common multiple of 667,814,819,561,729 is 612305387694.
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.
667 x 814 x 819 x 561 x 729 = 181854700145118
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.
667 : 1, 23, 29, 667
814 : 1, 2, 11, 22, 37, 74, 407, 814
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
561 : 1, 3, 11, 17, 33, 51, 187, 561
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,814,819,561,729, is 1.
Now, the common factors can be found like this.
667:23x 29
814:2x 11x 37
819:3x 3x 7x 13
561:3x 11x 17
729:3x 3x 3x 3x 3x 3
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 11 = 297
Therefore, the value for common factors is 297.
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 = 181854700145118/(1x297)
LCM = 181854700145118/297
LCM = 612305387694
Thus, we can understand that the LCM of 667,814,819,561,729 is 612305387694.
