Given numbers are 869,627,819,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,627,819,217 is 419197779.
Find LCM of 869,627,819,217 with Prime Factorization
3 | 869, 627, 819, 217 |
7 | 869, 209, 273, 217 |
11 | 869, 209, 39, 31 |
79, 19, 39, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 79 x 19 x 39 x 31 = 419197779
Therefore, the lowest common multiple of 869,627,819,217 is 419197779.
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.
869 x 627 x 819 x 217 = 96834686949
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.
869 : 1, 11, 79, 869
627 : 1, 3, 11, 19, 33, 57, 209, 627
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,627,819,217, is 1.
Now, the common factors can be found like this.
869:11x 79
627:3x 11x 19
819:3x 3x 7x 13
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 96834686949/(1x231)
LCM = 96834686949/231
LCM = 419197779
Thus, we can understand that the LCM of 869,627,819,217 is 419197779.
