Given numbers are 866,309,243,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,309,243,720 is 867004560.
Find LCM of 866,309,243,720 with Prime Factorization
| 2 | 866, 309, 243, 720 |
| 3 | 433, 309, 243, 360 |
| 3 | 433, 103, 81, 120 |
| 433, 103, 27, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 433 x 103 x 27 x 40 = 867004560
Therefore, the lowest common multiple of 866,309,243,720 is 867004560.
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.
866 x 309 x 243 x 720 = 46818246240
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.
866 : 1, 2, 433, 866
309 : 1, 3, 103, 309
243 : 1, 3, 9, 27, 81, 243
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,309,243,720, is 1.
Now, the common factors can be found like this.
866:2x 433
309:3x 103
243:3x 3x 3x 3x 3
720:2x 2x 2x 2x 3x 3x 5
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 3 = 54
Therefore, the value for common factors is 54.
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 = 46818246240/(1x54)
LCM = 46818246240/54
LCM = 867004560
Thus, we can understand that the LCM of 866,309,243,720 is 867004560.
