Find LCM of 230,644,449,408,768 with Prime Factorization
| 2 | 230, 644, 449, 408, 768 |
| 2 | 115, 322, 449, 204, 384 |
| 2 | 115, 161, 449, 102, 192 |
| 3 | 115, 161, 449, 51, 96 |
| 23 | 115, 161, 449, 17, 32 |
| 5, 7, 449, 17, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 5 x 7 x 449 x 17 x 32 = 4719025920
Therefore, the lowest common multiple of 230,644,449,408,768 is 4719025920.
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.
230 x 644 x 449 x 408 x 768 = 20839218462720
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
449 : 1, 449
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,644,449,408,768, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
644:2x 2x 7x 23
449:449
408:2x 2x 2x 3x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 23 = 4416
Therefore, the value for common factors is 4416.
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 = 20839218462720/(1x4416)
LCM = 20839218462720/4416
LCM = 4719025920
Thus, we can understand that the LCM of 230,644,449,408,768 is 4719025920.
