Given numbers are 561,573,939,990,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,573,939,990,703 is 707321966670.
Find LCM of 561,573,939,990,703 with Prime Factorization
| 3 | 561, 573, 939, 990, 703 |
| 11 | 187, 191, 313, 330, 703 |
| 17, 191, 313, 30, 703 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 191 x 313 x 30 x 703 = 707321966670
Therefore, the lowest common multiple of 561,573,939,990,703 is 707321966670.
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.
561 x 573 x 939 x 990 x 703 = 210074624100990
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
573 : 1, 3, 191, 573
939 : 1, 3, 313, 939
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,573,939,990,703, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
573:3x 191
939:3x 313
990:2x 3x 3x 5x 11
703:19x 37
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 11 = 297
Therefore, the value for common factors is 297.
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 = 210074624100990/(1x297)
LCM = 210074624100990/297
LCM = 707321966670
Thus, we can understand that the LCM of 561,573,939,990,703 is 707321966670.
