Given numbers are 34,89,68,12,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 34,89,68,12,561 is 199716.
Find LCM of 34,89,68,12,561 with Prime Factorization
| 2 | 34, 89, 68, 12, 561 |
| 2 | 17, 89, 34, 6, 561 |
| 3 | 17, 89, 17, 3, 561 |
| 17 | 17, 89, 17, 1, 187 |
| 1, 89, 1, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 1 x 89 x 1 x 1 x 11 = 199716
Therefore, the lowest common multiple of 34,89,68,12,561 is 199716.
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.
34 x 89 x 68 x 12 x 561 = 1385230176
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.
34 : 1, 2, 17, 34
89 : 1, 89
68 : 1, 2, 4, 17, 34, 68
12 : 1, 2, 3, 4, 6, 12
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 34,89,68,12,561, is 1.
Now, the common factors can be found like this.
34:2x 17
89:89
68:2x 2x 17
12:2x 2x 3
561:3x 11x 17
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 2x 3x 17x 17 = 6936
Therefore, the value for common factors is 6936.
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 = 1385230176/(1x6936)
LCM = 1385230176/6936
LCM = 199716
Thus, we can understand that the LCM of 34,89,68,12,561 is 199716.
