Given numbers are 561,121,234,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,121,234,481 is 17809506.
Find LCM of 561,121,234,481 with Prime Factorization
| 3 | 561, 121, 234, 481 |
| 11 | 187, 121, 78, 481 |
| 13 | 17, 11, 78, 481 |
| 17, 11, 6, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 17 x 11 x 6 x 37 = 17809506
Therefore, the lowest common multiple of 561,121,234,481 is 17809506.
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 121 x 234 x 481 = 7640278074
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
121 : 1, 11, 121
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,121,234,481, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
121:11x 11
234:2x 3x 3x 13
481:13x 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 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 7640278074/(1x429)
LCM = 7640278074/429
LCM = 17809506
Thus, we can understand that the LCM of 561,121,234,481 is 17809506.
