The LCM of 384,392,851,851 is 16012416.
Find LCM of 384,392,851,851 with Prime Factorization
| 2 | 384, 392, 851, 851 |
| 2 | 192, 196, 851, 851 |
| 2 | 96, 98, 851, 851 |
| 23 | 48, 49, 851, 851 |
| 37 | 48, 49, 37, 37 |
| 48, 49, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 37 x 48 x 49 x 1 x 1 = 16012416
Therefore, the lowest common multiple of 384,392,851,851 is 16012416.
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 392 x 851 x 851 = 109012528128
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
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
851 : 1, 23, 37, 851
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,392,851,851, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
392:2x 2x 2x 7x 7
851:23x 37
851:23x 37
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 23x 37 = 6808
Therefore, the value for common factors is 6808.
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 = 109012528128/(1x6808)
LCM = 109012528128/6808
LCM = 16012416
Thus, we can understand that the LCM of 384,392,851,851 is 16012416.
