Find LCM of 855,578,285,464 with Prime Factorization
| 2 | 855, 578, 285, 464 |
| 3 | 855, 289, 285, 232 |
| 5 | 95, 289, 285, 232 |
| 19 | 19, 289, 57, 232 |
| 1, 289, 3, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 289 x 3 x 232 = 114652080
Therefore, the lowest common multiple of 855,578,285,464 is 114652080.
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 578 x 285 x 464 = 65351685600
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
578 : 1, 2, 17, 34, 289, 578
285 : 1, 3, 5, 15, 19, 57, 95, 285
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,578,285,464, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
578:2x 17x 17
285:3x 5x 19
464:2x 2x 2x 2x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 19 = 570
Therefore, the value for common factors is 570.
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 = 65351685600/(1x570)
LCM = 65351685600/570
LCM = 114652080
Thus, we can understand that the LCM of 855,578,285,464 is 114652080.
