Given numbers are 561,55,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,55,474 is 443190.
Find LCM of 561,55,474 with Prime Factorization
| 3 | 561, 55, 474 |
| 11 | 187, 55, 158 |
| 17, 5, 158 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 5 x 158 = 443190
Therefore, the lowest common multiple of 561,55,474 is 443190.
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 55 x 474 = 14625270
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
55 : 1, 5, 11, 55
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,55,474, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
55:5x 11
474:2x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 14625270/(1x33)
LCM = 14625270/33
LCM = 443190
Thus, we can understand that the LCM of 561,55,474 is 443190.
