Find LCM of 330,308,242,672,289 with Prime Factorization
| 2 | 330, 308, 242, 672, 289 |
| 2 | 165, 154, 121, 336, 289 |
| 3 | 165, 77, 121, 168, 289 |
| 7 | 55, 77, 121, 56, 289 |
| 11 | 55, 11, 121, 8, 289 |
| 5, 1, 11, 8, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 5 x 1 x 11 x 8 x 289 = 117495840
Therefore, the lowest common multiple of 330,308,242,672,289 is 117495840.
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.
330 x 308 x 242 x 672 x 289 = 4776910871040
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
242 : 1, 2, 11, 22, 121, 242
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,308,242,672,289, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
308:2x 2x 7x 11
242:2x 11x 11
672:2x 2x 2x 2x 2x 3x 7
289:17x 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 3x 7x 11x 11 = 40656
Therefore, the value for common factors is 40656.
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 = 4776910871040/(1x40656)
LCM = 4776910871040/40656
LCM = 117495840
Thus, we can understand that the LCM of 330,308,242,672,289 is 117495840.
