Given numbers are 853,963,311,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,963,311,747 is 21203804907.
Find LCM of 853,963,311,747 with Prime Factorization
| 3 | 853, 963, 311, 747 |
| 3 | 853, 321, 311, 249 |
| 853, 107, 311, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 853 x 107 x 311 x 83 = 21203804907
Therefore, the lowest common multiple of 853,963,311,747 is 21203804907.
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.
853 x 963 x 311 x 747 = 190834244163
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.
853 : 1, 853
963 : 1, 3, 9, 107, 321, 963
311 : 1, 311
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,963,311,747, is 1.
Now, the common factors can be found like this.
853:853
963:3x 3x 107
311:311
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 190834244163/(1x9)
LCM = 190834244163/9
LCM = 21203804907
Thus, we can understand that the LCM of 853,963,311,747 is 21203804907.
