Find LCM of 768,996,661,208 with Prime Factorization
| 2 | 768, 996, 661, 208 |
| 2 | 384, 498, 661, 104 |
| 2 | 192, 249, 661, 52 |
| 2 | 96, 249, 661, 26 |
| 3 | 48, 249, 661, 13 |
| 16, 83, 661, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 16 x 83 x 661 x 13 = 547752192
Therefore, the lowest common multiple of 768,996,661,208 is 547752192.
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.
768 x 996 x 661 x 208 = 105168420864
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
661 : 1, 661
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,996,661,208, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
996:2x 2x 3x 83
661:661
208:2x 2x 2x 2x 13
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 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 105168420864/(1x192)
LCM = 105168420864/192
LCM = 547752192
Thus, we can understand that the LCM of 768,996,661,208 is 547752192.
