Given numbers are 81,91,55,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 81,91,55,611 is 19054035.
Find LCM of 81,91,55,611 with Prime Factorization
13 | 81, 91, 55, 611 |
81, 7, 55, 47 |
Multiply the prime numbers at the bottom and the left side.
13 x 81 x 7 x 55 x 47 = 19054035
Therefore, the lowest common multiple of 81,91,55,611 is 19054035.
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.
81 x 91 x 55 x 611 = 247702455
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.
81 : 1, 3, 9, 27, 81
91 : 1, 7, 13, 91
55 : 1, 5, 11, 55
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 81,91,55,611, is 1.
Now, the common factors can be found like this.
81:3x 3x 3x 3
91:7x 13
55:5x 11
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 247702455/(1x13)
LCM = 247702455/13
LCM = 19054035
Thus, we can understand that the LCM of 81,91,55,611 is 19054035.
