Find LCM of 871,856,783,504 with Prime Factorization
| 2 | 871, 856, 783, 504 |
| 2 | 871, 428, 783, 252 |
| 2 | 871, 214, 783, 126 |
| 3 | 871, 107, 783, 63 |
| 3 | 871, 107, 261, 21 |
| 871, 107, 87, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 871 x 107 x 87 x 7 = 4086502056
Therefore, the lowest common multiple of 871,856,783,504 is 4086502056.
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.
871 x 856 x 783 x 504 = 294228148032
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.
871 : 1, 13, 67, 871
856 : 1, 2, 4, 8, 107, 214, 428, 856
783 : 1, 3, 9, 27, 29, 87, 261, 783
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,856,783,504, is 1.
Now, the common factors can be found like this.
871:13x 67
856:2x 2x 2x 107
783:3x 3x 3x 29
504:2x 2x 2x 3x 3x 7
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 294228148032/(1x72)
LCM = 294228148032/72
LCM = 4086502056
Thus, we can understand that the LCM of 871,856,783,504 is 4086502056.
