Given numbers are 686,532,760,227,205
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,532,760,227,205 is 2426148760.
Find LCM of 686,532,760,227,205 with Prime Factorization
| 2 | 686, 532, 760, 227, 205 |
| 2 | 343, 266, 380, 227, 205 |
| 5 | 343, 133, 190, 227, 205 |
| 7 | 343, 133, 38, 227, 41 |
| 19 | 49, 19, 38, 227, 41 |
| 49, 1, 2, 227, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 49 x 1 x 2 x 227 x 41 = 2426148760
Therefore, the lowest common multiple of 686,532,760,227,205 is 2426148760.
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.
686 x 532 x 760 x 227 x 205 = 12907111403200
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
227 : 1, 227
205 : 1, 5, 41, 205
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,532,760,227,205, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
532:2x 2x 7x 19
760:2x 2x 2x 5x 19
227:227
205:5x 41
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 5x 7x 19 = 5320
Therefore, the value for common factors is 5320.
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 = 12907111403200/(1x5320)
LCM = 12907111403200/5320
LCM = 2426148760
Thus, we can understand that the LCM of 686,532,760,227,205 is 2426148760.
