Given numbers are 194,682,960,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 194,682,960,561 is 539816640.
Find LCM of 194,682,960,561 with Prime Factorization
| 2 | 194, 682, 960, 561 |
| 3 | 97, 341, 480, 561 |
| 11 | 97, 341, 160, 187 |
| 97, 31, 160, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 97 x 31 x 160 x 17 = 539816640
Therefore, the lowest common multiple of 194,682,960,561 is 539816640.
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.
194 x 682 x 960 x 561 = 71255796480
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.
194 : 1, 2, 97, 194
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,682,960,561, is 1.
Now, the common factors can be found like this.
194:2x 97
682:2x 11x 31
960:2x 2x 2x 2x 2x 2x 3x 5
561:3x 11x 17
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 71255796480/(1x132)
LCM = 71255796480/132
LCM = 539816640
Thus, we can understand that the LCM of 194,682,960,561 is 539816640.
