Given numbers are 923,405,121,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,405,121,147 is 2216349135.
Find LCM of 923,405,121,147 with Prime Factorization
3 | 923, 405, 121, 147 |
923, 135, 121, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 923 x 135 x 121 x 49 = 2216349135
Therefore, the lowest common multiple of 923,405,121,147 is 2216349135.
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.
923 x 405 x 121 x 147 = 6649047405
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.
923 : 1, 13, 71, 923
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
121 : 1, 11, 121
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,405,121,147, is 1.
Now, the common factors can be found like this.
923:13x 71
405:3x 3x 3x 3x 5
121:11x 11
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 6649047405/(1x3)
LCM = 6649047405/3
LCM = 2216349135
Thus, we can understand that the LCM of 923,405,121,147 is 2216349135.
