Find LCM of 242,960,838,672 with Prime Factorization
| 2 | 242, 960, 838, 672 |
| 2 | 121, 480, 419, 336 |
| 2 | 121, 240, 419, 168 |
| 2 | 121, 120, 419, 84 |
| 2 | 121, 60, 419, 42 |
| 3 | 121, 30, 419, 21 |
| 121, 10, 419, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 121 x 10 x 419 x 7 = 340697280
Therefore, the lowest common multiple of 242,960,838,672 is 340697280.
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.
242 x 960 x 838 x 672 = 130827755520
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.
242 : 1, 2, 11, 22, 121, 242
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
838 : 1, 2, 419, 838
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,960,838,672, is 2.
Now, the common factors can be found like this.
242:2x 11x 11
960:2x 2x 2x 2x 2x 2x 3x 5
838:2x 419
672:2x 2x 2x 2x 2x 3x 7
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 = 130827755520/(2x192)
LCM = 130827755520/384
LCM = 340697280
Thus, we can understand that the LCM of 242,960,838,672 is 340697280.
