Find LCM of 221,289,768,216 with Prime Factorization
2 | 221, 289, 768, 216 |
2 | 221, 289, 384, 108 |
2 | 221, 289, 192, 54 |
3 | 221, 289, 96, 27 |
17 | 221, 289, 32, 9 |
13, 17, 32, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 13 x 17 x 32 x 9 = 25968384
Therefore, the lowest common multiple of 221,289,768,216 is 25968384.
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.
221 x 289 x 768 x 216 = 10595100672
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.
221 : 1, 13, 17, 221
289 : 1, 17, 289
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,289,768,216, is 1.
Now, the common factors can be found like this.
221:13x 17
289:17x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
216:2x 2x 2x 3x 3x 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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 10595100672/(1x408)
LCM = 10595100672/408
LCM = 25968384
Thus, we can understand that the LCM of 221,289,768,216 is 25968384.
