The LCM of 809,403,759,897 is 247454493.
Find LCM of 809,403,759,897 with Prime Factorization
| 3 | 809, 403, 759, 897 |
| 13 | 809, 403, 253, 299 |
| 23 | 809, 31, 253, 23 |
| 809, 31, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 809 x 31 x 11 x 1 = 247454493
Therefore, the lowest common multiple of 809,403,759,897 is 247454493.
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 403 x 759 x 897 = 221966680221
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
403 : 1, 13, 31, 403
759 : 1, 3, 11, 23, 33, 69, 253, 759
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,403,759,897, is 1.
Now, the common factors can be found like this.
809:809
403:13x 31
759:3x 11x 23
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 23 = 897
Therefore, the value for common factors is 897.
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 = 221966680221/(1x897)
LCM = 221966680221/897
LCM = 247454493
Thus, we can understand that the LCM of 809,403,759,897 is 247454493.
