Given numbers are 856,771,964,656,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,771,964,656,494 is 3221484090864.
Find LCM of 856,771,964,656,494 with Prime Factorization
| 2 | 856, 771, 964, 656, 494 |
| 2 | 428, 771, 482, 328, 247 |
| 2 | 214, 771, 241, 164, 247 |
| 107, 771, 241, 82, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 107 x 771 x 241 x 82 x 247 = 3221484090864
Therefore, the lowest common multiple of 856,771,964,656,494 is 3221484090864.
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.
856 x 771 x 964 x 656 x 494 = 206174981815296
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
771 : 1, 3, 257, 771
964 : 1, 2, 4, 241, 482, 964
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,771,964,656,494, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
771:3x 257
964:2x 2x 241
656:2x 2x 2x 2x 41
494:2x 13x 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 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 206174981815296/(1x64)
LCM = 206174981815296/64
LCM = 3221484090864
Thus, we can understand that the LCM of 856,771,964,656,494 is 3221484090864.
