The LCM of 384,488,505,475,642 is 120243004800.
Find LCM of 384,488,505,475,642 with Prime Factorization
| 2 | 384, 488, 505, 475, 642 |
| 2 | 192, 244, 505, 475, 321 |
| 2 | 96, 122, 505, 475, 321 |
| 3 | 48, 61, 505, 475, 321 |
| 5 | 16, 61, 505, 475, 107 |
| 16, 61, 101, 95, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 16 x 61 x 101 x 95 x 107 = 120243004800
Therefore, the lowest common multiple of 384,488,505,475,642 is 120243004800.
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.
384 x 488 x 505 x 475 x 642 = 28858321152000
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
488 : 1, 2, 4, 8, 61, 122, 244, 488
505 : 1, 5, 101, 505
475 : 1, 5, 19, 25, 95, 475
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,488,505,475,642, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
488:2x 2x 2x 61
505:5x 101
475:5x 5x 19
642:2x 3x 107
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 28858321152000/(1x240)
LCM = 28858321152000/240
LCM = 120243004800
Thus, we can understand that the LCM of 384,488,505,475,642 is 120243004800.
