Given numbers are 821,866,815,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,866,815,955 is 110675635690.
Find LCM of 821,866,815,955 with Prime Factorization
| 5 | 821, 866, 815, 955 |
| 821, 866, 163, 191 |
Multiply the prime numbers at the bottom and the left side.
5 x 821 x 866 x 163 x 191 = 110675635690
Therefore, the lowest common multiple of 821,866,815,955 is 110675635690.
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.
821 x 866 x 815 x 955 = 553378178450
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.
821 : 1, 821
866 : 1, 2, 433, 866
815 : 1, 5, 163, 815
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,866,815,955, is 1.
Now, the common factors can be found like this.
821:821
866:2x 433
815:5x 163
955:5x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 553378178450/(1x5)
LCM = 553378178450/5
LCM = 110675635690
Thus, we can understand that the LCM of 821,866,815,955 is 110675635690.
