Given numbers are 905,521,891,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,521,891,181 is 420110955.
Find LCM of 905,521,891,181 with Prime Factorization
181 | 905, 521, 891, 181 |
5, 521, 891, 1 |
Multiply the prime numbers at the bottom and the left side.
181 x 5 x 521 x 891 x 1 = 420110955
Therefore, the lowest common multiple of 905,521,891,181 is 420110955.
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.
905 x 521 x 891 x 181 = 76040082855
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.
905 : 1, 5, 181, 905
521 : 1, 521
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,521,891,181, is 1.
Now, the common factors can be found like this.
905:5x 181
521:521
891:3x 3x 3x 3x 11
181:181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
181 = 181
Therefore, the value for common factors is 181.
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 = 76040082855/(1x181)
LCM = 76040082855/181
LCM = 420110955
Thus, we can understand that the LCM of 905,521,891,181 is 420110955.
