Find LCM of 285,663,752,364,855 with Prime Factorization
| 2 | 285, 663, 752, 364, 855 |
| 2 | 285, 663, 376, 182, 855 |
| 3 | 285, 663, 188, 91, 855 |
| 5 | 95, 221, 188, 91, 285 |
| 13 | 19, 221, 188, 91, 57 |
| 19 | 19, 17, 188, 7, 57 |
| 1, 17, 188, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 19 x 1 x 17 x 188 x 7 x 3 = 994659120
Therefore, the lowest common multiple of 285,663,752,364,855 is 994659120.
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.
285 x 663 x 752 x 364 x 855 = 44222544475200
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
663 : 1, 3, 13, 17, 39, 51, 221, 663
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,663,752,364,855, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
663:3x 13x 17
752:2x 2x 2x 2x 47
364:2x 2x 7x 13
855:3x 3x 5x 19
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 3x 3x 5x 13x 19 = 44460
Therefore, the value for common factors is 44460.
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 = 44222544475200/(1x44460)
LCM = 44222544475200/44460
LCM = 994659120
Thus, we can understand that the LCM of 285,663,752,364,855 is 994659120.
