Given numbers are 957,561,822,609,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,561,822,609,687 is 7145702718.
Find LCM of 957,561,822,609,687 with Prime Factorization
| 3 | 957, 561, 822, 609, 687 |
| 11 | 319, 187, 274, 203, 229 |
| 29 | 29, 17, 274, 203, 229 |
| 1, 17, 274, 7, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 29 x 1 x 17 x 274 x 7 x 229 = 7145702718
Therefore, the lowest common multiple of 957,561,822,609,687 is 7145702718.
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.
957 x 561 x 822 x 609 x 687 = 184637812530402
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
561 : 1, 3, 11, 17, 33, 51, 187, 561
822 : 1, 2, 3, 6, 137, 274, 411, 822
609 : 1, 3, 7, 21, 29, 87, 203, 609
687 : 1, 3, 229, 687
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,561,822,609,687, is 3.
Now, the common factors can be found like this.
957:3x 11x 29
561:3x 11x 17
822:2x 3x 137
609:3x 7x 29
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11x 29 = 8613
Therefore, the value for common factors is 8613.
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 = 184637812530402/(3x8613)
LCM = 184637812530402/25839
LCM = 7145702718
Thus, we can understand that the LCM of 957,561,822,609,687 is 7145702718.
