Given numbers are 102,969,836,866
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,969,836,866 is 18461388.
Find LCM of 102,969,836,866 with Prime Factorization
| 2 | 102, 969, 836, 866 |
| 3 | 51, 969, 418, 433 |
| 17 | 17, 323, 418, 433 |
| 19 | 1, 19, 418, 433 |
| 1, 1, 22, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 1 x 1 x 22 x 433 = 18461388
Therefore, the lowest common multiple of 102,969,836,866 is 18461388.
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.
102 x 969 x 836 x 866 = 71556339888
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
969 : 1, 3, 17, 19, 51, 57, 323, 969
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
866 : 1, 2, 433, 866
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,969,836,866, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
969:3x 17x 19
836:2x 2x 11x 19
866:2x 433
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 17x 19 = 3876
Therefore, the value for common factors is 3876.
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 = 71556339888/(1x3876)
LCM = 71556339888/3876
LCM = 18461388
Thus, we can understand that the LCM of 102,969,836,866 is 18461388.
