The LCM of 693,381,705,729,973 is 232865224515.
Find LCM of 693,381,705,729,973 with Prime Factorization
| 3 | 693, 381, 705, 729, 973 |
| 3 | 231, 127, 235, 243, 973 |
| 7 | 77, 127, 235, 81, 973 |
| 11, 127, 235, 81, 139 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 127 x 235 x 81 x 139 = 232865224515
Therefore, the lowest common multiple of 693,381,705,729,973 is 232865224515.
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.
693 x 381 x 705 x 729 x 973 = 132034582300005
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
381 : 1, 3, 127, 381
705 : 1, 3, 5, 15, 47, 141, 235, 705
729 : 1, 3, 9, 27, 81, 243, 729
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,381,705,729,973, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
381:3x 127
705:3x 5x 47
729:3x 3x 3x 3x 3x 3
973:7x 139
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 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 132034582300005/(1x567)
LCM = 132034582300005/567
LCM = 232865224515
Thus, we can understand that the LCM of 693,381,705,729,973 is 232865224515.
