Given numbers are 66,33,81,55,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 66,33,81,55,387 is 383130.
Find LCM of 66,33,81,55,387 with Prime Factorization
| 3 | 66, 33, 81, 55, 387 |
| 3 | 22, 11, 27, 55, 129 |
| 11 | 22, 11, 9, 55, 43 |
| 2, 1, 9, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 2 x 1 x 9 x 5 x 43 = 383130
Therefore, the lowest common multiple of 66,33,81,55,387 is 383130.
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.
66 x 33 x 81 x 55 x 387 = 3755057130
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.
66 : 1, 2, 3, 6, 11, 22, 33, 66
33 : 1, 3, 11, 33
81 : 1, 3, 9, 27, 81
55 : 1, 5, 11, 55
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 66,33,81,55,387, is 1.
Now, the common factors can be found like this.
66:2x 3x 11
33:3x 11
81:3x 3x 3x 3
55:5x 11
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 11x 11 = 9801
Therefore, the value for common factors is 9801.
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 = 3755057130/(1x9801)
LCM = 3755057130/9801
LCM = 383130
Thus, we can understand that the LCM of 66,33,81,55,387 is 383130.
