Find LCM of 866,809,988,798,385 with Prime Factorization
| 2 | 866, 809, 988, 798, 385 |
| 7 | 433, 809, 494, 399, 385 |
| 19 | 433, 809, 494, 57, 55 |
| 433, 809, 26, 3, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 433 x 809 x 26 x 3 x 55 = 399737918580
Therefore, the lowest common multiple of 866,809,988,798,385 is 399737918580.
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.
866 x 809 x 988 x 798 x 385 = 212660572684560
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.
866 : 1, 2, 433, 866
809 : 1, 809
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,809,988,798,385, is 1.
Now, the common factors can be found like this.
866:2x 433
809:809
988:2x 2x 13x 19
798:2x 3x 7x 19
385:5x 7x 11
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 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 212660572684560/(1x532)
LCM = 212660572684560/532
LCM = 399737918580
Thus, we can understand that the LCM of 866,809,988,798,385 is 399737918580.
