Given numbers are 561,818,853,717,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,818,853,717,189 is 5893911989658.
Find LCM of 561,818,853,717,189 with Prime Factorization
| 3 | 561, 818, 853, 717, 189 |
| 187, 818, 853, 239, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 187 x 818 x 853 x 239 x 63 = 5893911989658
Therefore, the lowest common multiple of 561,818,853,717,189 is 5893911989658.
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 818 x 853 x 717 x 189 = 53045207906922
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
818 : 1, 2, 409, 818
853 : 1, 853
717 : 1, 3, 239, 717
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,818,853,717,189, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
818:2x 409
853:853
717:3x 239
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 53045207906922/(1x9)
LCM = 53045207906922/9
LCM = 5893911989658
Thus, we can understand that the LCM of 561,818,853,717,189 is 5893911989658.
