The LCM of 285,228,603,346,655 is 5192999820.
Find LCM of 285,228,603,346,655 with Prime Factorization
| 2 | 285, 228, 603, 346, 655 |
| 3 | 285, 114, 603, 173, 655 |
| 5 | 95, 38, 201, 173, 655 |
| 19 | 19, 38, 201, 173, 131 |
| 1, 2, 201, 173, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 2 x 201 x 173 x 131 = 5192999820
Therefore, the lowest common multiple of 285,228,603,346,655 is 5192999820.
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 228 x 603 x 346 x 655 = 8880029692200
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
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
603 : 1, 3, 9, 67, 201, 603
346 : 1, 2, 173, 346
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,228,603,346,655, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
228:2x 2x 3x 19
603:3x 3x 67
346:2x 173
655:5x 131
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 3x 5x 19 = 1710
Therefore, the value for common factors is 1710.
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 = 8880029692200/(1x1710)
LCM = 8880029692200/1710
LCM = 5192999820
Thus, we can understand that the LCM of 285,228,603,346,655 is 5192999820.
