Find LCM of 546,784,522,512 with Prime Factorization
| 2 | 546, 784, 522, 512 |
| 2 | 273, 392, 261, 256 |
| 2 | 273, 196, 261, 128 |
| 2 | 273, 98, 261, 64 |
| 3 | 273, 49, 261, 32 |
| 7 | 91, 49, 87, 32 |
| 13, 7, 87, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 13 x 7 x 87 x 32 = 85123584
Therefore, the lowest common multiple of 546,784,522,512 is 85123584.
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.
546 x 784 x 522 x 512 = 114406096896
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,784,522,512, is 2.
Now, the common factors can be found like this.
546:2x 3x 7x 13
784:2x 2x 2x 2x 7x 7
522:2x 3x 3x 29
512:2x 2x 2x 2x 2x 2x 2x 2x 2
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 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 114406096896/(2x672)
LCM = 114406096896/1344
LCM = 85123584
Thus, we can understand that the LCM of 546,784,522,512 is 85123584.
