Find LCM of 985,864,939,272 with Prime Factorization
| 2 | 985, 864, 939, 272 |
| 2 | 985, 432, 939, 136 |
| 2 | 985, 216, 939, 68 |
| 2 | 985, 108, 939, 34 |
| 3 | 985, 54, 939, 17 |
| 985, 18, 313, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 985 x 18 x 313 x 17 = 4528383840
Therefore, the lowest common multiple of 985,864,939,272 is 4528383840.
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.
985 x 864 x 939 x 272 = 217362424320
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.
985 : 1, 5, 197, 985
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
939 : 1, 3, 313, 939
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,864,939,272, is 1.
Now, the common factors can be found like this.
985:5x 197
864:2x 2x 2x 2x 2x 3x 3x 3
939:3x 313
272:2x 2x 2x 2x 17
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 3 = 48
Therefore, the value for common factors is 48.
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 = 217362424320/(1x48)
LCM = 217362424320/48
LCM = 4528383840
Thus, we can understand that the LCM of 985,864,939,272 is 4528383840.
