Given numbers are 682,960,561,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,960,561,961 is 172518720.
Find LCM of 682,960,561,961 with Prime Factorization
| 2 | 682, 960, 561, 961 |
| 3 | 341, 480, 561, 961 |
| 11 | 341, 160, 187, 961 |
| 31 | 31, 160, 17, 961 |
| 1, 160, 17, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 31 x 1 x 160 x 17 x 31 = 172518720
Therefore, the lowest common multiple of 682,960,561,961 is 172518720.
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.
682 x 960 x 561 x 961 = 352973301120
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
561 : 1, 3, 11, 17, 33, 51, 187, 561
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,960,561,961, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
960:2x 2x 2x 2x 2x 2x 3x 5
561:3x 11x 17
961:31x 31
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 11x 31 = 2046
Therefore, the value for common factors is 2046.
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 = 352973301120/(1x2046)
LCM = 352973301120/2046
LCM = 172518720
Thus, we can understand that the LCM of 682,960,561,961 is 172518720.
