Given numbers are 561,326,726,332,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,326,726,332,389 is 129906486204.
Find LCM of 561,326,726,332,389 with Prime Factorization
| 2 | 561, 326, 726, 332, 389 |
| 3 | 561, 163, 363, 166, 389 |
| 11 | 187, 163, 121, 166, 389 |
| 17, 163, 11, 166, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 163 x 11 x 166 x 389 = 129906486204
Therefore, the lowest common multiple of 561,326,726,332,389 is 129906486204.
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 326 x 726 x 332 x 389 = 17147656178928
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
326 : 1, 2, 163, 326
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
332 : 1, 2, 4, 83, 166, 332
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,326,726,332,389, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
326:2x 163
726:2x 3x 11x 11
332:2x 2x 83
389:389
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 = 17147656178928/(1x132)
LCM = 17147656178928/132
LCM = 129906486204
Thus, we can understand that the LCM of 561,326,726,332,389 is 129906486204.
