The LCM of 673,871,495,231,815 is 331073227485.
Find LCM of 673,871,495,231,815 with Prime Factorization
| 3 | 673, 871, 495, 231, 815 |
| 5 | 673, 871, 165, 77, 815 |
| 11 | 673, 871, 33, 77, 163 |
| 673, 871, 3, 7, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 673 x 871 x 3 x 7 x 163 = 331073227485
Therefore, the lowest common multiple of 673,871,495,231,815 is 331073227485.
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.
673 x 871 x 495 x 231 x 815 = 54627082535025
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.
673 : 1, 673
871 : 1, 13, 67, 871
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
231 : 1, 3, 7, 11, 21, 33, 77, 231
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,871,495,231,815, is 1.
Now, the common factors can be found like this.
673:673
871:13x 67
495:3x 3x 5x 11
231:3x 7x 11
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 54627082535025/(1x165)
LCM = 54627082535025/165
LCM = 331073227485
Thus, we can understand that the LCM of 673,871,495,231,815 is 331073227485.
