Given numbers are 727,171,921,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 727,171,921,289 is 11029777191.
Find LCM of 727,171,921,289 with Prime Factorization
| 3 | 727, 171, 921, 289 |
| 727, 57, 307, 289 |
Multiply the prime numbers at the bottom and the left side.
3 x 727 x 57 x 307 x 289 = 11029777191
Therefore, the lowest common multiple of 727,171,921,289 is 11029777191.
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.
727 x 171 x 921 x 289 = 33089331573
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.
727 : 1, 727
171 : 1, 3, 9, 19, 57, 171
921 : 1, 3, 307, 921
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,171,921,289, is 1.
Now, the common factors can be found like this.
727:727
171:3x 3x 19
921:3x 307
289:17x 17
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 = 33089331573/(1x3)
LCM = 33089331573/3
LCM = 11029777191
Thus, we can understand that the LCM of 727,171,921,289 is 11029777191.
