Given numbers are 269,243,689,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 269,243,689,921 is 13826623941.
Find LCM of 269,243,689,921 with Prime Factorization
| 3 | 269, 243, 689, 921 |
| 269, 81, 689, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 269 x 81 x 689 x 307 = 13826623941
Therefore, the lowest common multiple of 269,243,689,921 is 13826623941.
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.
269 x 243 x 689 x 921 = 41479871823
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.
269 : 1, 269
243 : 1, 3, 9, 27, 81, 243
689 : 1, 13, 53, 689
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,243,689,921, is 1.
Now, the common factors can be found like this.
269:269
243:3x 3x 3x 3x 3
689:13x 53
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 41479871823/(1x3)
LCM = 41479871823/3
LCM = 13826623941
Thus, we can understand that the LCM of 269,243,689,921 is 13826623941.
