Given numbers are 261,205,992,620,344
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,205,992,620,344 is 2282309280.
Find LCM of 261,205,992,620,344 with Prime Factorization
| 2 | 261, 205, 992, 620, 344 |
| 2 | 261, 205, 496, 310, 172 |
| 2 | 261, 205, 248, 155, 86 |
| 5 | 261, 205, 124, 155, 43 |
| 31 | 261, 41, 124, 31, 43 |
| 261, 41, 4, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 31 x 261 x 41 x 4 x 1 x 43 = 2282309280
Therefore, the lowest common multiple of 261,205,992,620,344 is 2282309280.
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.
261 x 205 x 992 x 620 x 344 = 11320254028800
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.
261 : 1, 3, 9, 29, 87, 261
205 : 1, 5, 41, 205
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,205,992,620,344, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
205:5x 41
992:2x 2x 2x 2x 2x 31
620:2x 2x 5x 31
344:2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 5x 31 = 4960
Therefore, the value for common factors is 4960.
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 = 11320254028800/(1x4960)
LCM = 11320254028800/4960
LCM = 2282309280
Thus, we can understand that the LCM of 261,205,992,620,344 is 2282309280.
