The LCM of 855,247,871,404,711 is 23768004780.
Find LCM of 855,247,871,404,711 with Prime Factorization
| 3 | 855, 247, 871, 404, 711 |
| 3 | 285, 247, 871, 404, 237 |
| 13 | 95, 247, 871, 404, 79 |
| 19 | 95, 19, 67, 404, 79 |
| 5, 1, 67, 404, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 19 x 5 x 1 x 67 x 404 x 79 = 23768004780
Therefore, the lowest common multiple of 855,247,871,404,711 is 23768004780.
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.
855 x 247 x 871 x 404 x 711 = 52836274625940
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
247 : 1, 13, 19, 247
871 : 1, 13, 67, 871
404 : 1, 2, 4, 101, 202, 404
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,247,871,404,711, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
247:13x 19
871:13x 67
404:2x 2x 101
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 19 = 2223
Therefore, the value for common factors is 2223.
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 = 52836274625940/(1x2223)
LCM = 52836274625940/2223
LCM = 23768004780
Thus, we can understand that the LCM of 855,247,871,404,711 is 23768004780.
