Given numbers are 847,121,865,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,121,865,313 is 229321015.
Find LCM of 847,121,865,313 with Prime Factorization
| 11 | 847, 121, 865, 313 |
| 11 | 77, 11, 865, 313 |
| 7, 1, 865, 313 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 7 x 1 x 865 x 313 = 229321015
Therefore, the lowest common multiple of 847,121,865,313 is 229321015.
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.
847 x 121 x 865 x 313 = 27747842815
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.
847 : 1, 7, 11, 77, 121, 847
121 : 1, 11, 121
865 : 1, 5, 173, 865
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,121,865,313, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
121:11x 11
865:5x 173
313:313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 27747842815/(1x121)
LCM = 27747842815/121
LCM = 229321015
Thus, we can understand that the LCM of 847,121,865,313 is 229321015.
