Given numbers are 788,551,836,857,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,551,836,857,764 is 781780242716.
Find LCM of 788,551,836,857,764 with Prime Factorization
| 2 | 788, 551, 836, 857, 764 |
| 2 | 394, 551, 418, 857, 382 |
| 19 | 197, 551, 209, 857, 191 |
| 197, 29, 11, 857, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 197 x 29 x 11 x 857 x 191 = 781780242716
Therefore, the lowest common multiple of 788,551,836,857,764 is 781780242716.
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.
788 x 551 x 836 x 857 x 764 = 237661193785664
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.
788 : 1, 2, 4, 197, 394, 788
551 : 1, 19, 29, 551
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
857 : 1, 857
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,551,836,857,764, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
551:19x 29
836:2x 2x 11x 19
857:857
764:2x 2x 191
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 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 237661193785664/(1x304)
LCM = 237661193785664/304
LCM = 781780242716
Thus, we can understand that the LCM of 788,551,836,857,764 is 781780242716.
