Given numbers are 561,198,622,669,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,198,622,669,897 is 69799217202.
Find LCM of 561,198,622,669,897 with Prime Factorization
| 2 | 561, 198, 622, 669, 897 |
| 3 | 561, 99, 311, 669, 897 |
| 11 | 187, 33, 311, 223, 299 |
| 17, 3, 311, 223, 299 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 3 x 311 x 223 x 299 = 69799217202
Therefore, the lowest common multiple of 561,198,622,669,897 is 69799217202.
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 198 x 622 x 669 x 897 = 41460735017988
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
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
622 : 1, 2, 311, 622
669 : 1, 3, 223, 669
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,198,622,669,897, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
198:2x 3x 3x 11
622:2x 311
669:3x 223
897:3x 13x 23
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 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 41460735017988/(1x594)
LCM = 41460735017988/594
LCM = 69799217202
Thus, we can understand that the LCM of 561,198,622,669,897 is 69799217202.
