Find LCM of 192,309,952,489,861 with Prime Factorization
| 2 | 192, 309, 952, 489, 861 |
| 2 | 96, 309, 476, 489, 861 |
| 2 | 48, 309, 238, 489, 861 |
| 3 | 24, 309, 119, 489, 861 |
| 7 | 8, 103, 119, 163, 287 |
| 8, 103, 17, 163, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 8 x 103 x 17 x 163 x 41 = 15727397952
Therefore, the lowest common multiple of 192,309,952,489,861 is 15727397952.
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.
192 x 309 x 952 x 489 x 861 = 23779825703424
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
309 : 1, 3, 103, 309
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
489 : 1, 3, 163, 489
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,309,952,489,861, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
309:3x 103
952:2x 2x 2x 7x 17
489:3x 163
861:3x 7x 41
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 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 23779825703424/(1x1512)
LCM = 23779825703424/1512
LCM = 15727397952
Thus, we can understand that the LCM of 192,309,952,489,861 is 15727397952.
