Find LCM of 855,946,868,928,288 with Prime Factorization
| 2 | 855, 946, 868, 928, 288 |
| 2 | 855, 473, 434, 464, 144 |
| 2 | 855, 473, 217, 232, 72 |
| 2 | 855, 473, 217, 116, 36 |
| 2 | 855, 473, 217, 58, 18 |
| 3 | 855, 473, 217, 29, 9 |
| 3 | 285, 473, 217, 29, 3 |
| 95, 473, 217, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 95 x 473 x 217 x 29 x 1 = 81439475040
Therefore, the lowest common multiple of 855,946,868,928,288 is 81439475040.
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 946 x 868 x 928 x 288 = 187636550492160
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
946 : 1, 2, 11, 22, 43, 86, 473, 946
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,946,868,928,288, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
946:2x 11x 43
868:2x 2x 7x 31
928:2x 2x 2x 2x 2x 29
288:2x 2x 2x 2x 2x 3x 3
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 2x 2x 2x 2x 2x 3x 3 = 2304
Therefore, the value for common factors is 2304.
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 = 187636550492160/(1x2304)
LCM = 187636550492160/2304
LCM = 81439475040
Thus, we can understand that the LCM of 855,946,868,928,288 is 81439475040.
