The LCM of 809,899,180,684 is 2487335220.
Find LCM of 809,899,180,684 with Prime Factorization
| 2 | 809, 899, 180, 684 |
| 2 | 809, 899, 90, 342 |
| 3 | 809, 899, 45, 171 |
| 3 | 809, 899, 15, 57 |
| 809, 899, 5, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 809 x 899 x 5 x 19 = 2487335220
Therefore, the lowest common multiple of 809,899,180,684 is 2487335220.
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.
809 x 899 x 180 x 684 = 89544067920
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.
809 : 1, 809
899 : 1, 29, 31, 899
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,899,180,684, is 1.
Now, the common factors can be found like this.
809:809
899:29x 31
180:2x 2x 3x 3x 5
684:2x 2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 89544067920/(1x36)
LCM = 89544067920/36
LCM = 2487335220
Thus, we can understand that the LCM of 809,899,180,684 is 2487335220.
