The LCM of 768,836,333,561 is 302886144.
Find LCM of 768,836,333,561 with Prime Factorization
| 2 | 768, 836, 333, 561 |
| 2 | 384, 418, 333, 561 |
| 3 | 192, 209, 333, 561 |
| 11 | 64, 209, 111, 187 |
| 64, 19, 111, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 64 x 19 x 111 x 17 = 302886144
Therefore, the lowest common multiple of 768,836,333,561 is 302886144.
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.
768 x 836 x 333 x 561 = 119942913024
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
333 : 1, 3, 9, 37, 111, 333
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,836,333,561, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
836:2x 2x 11x 19
333:3x 3x 37
561:3x 11x 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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 119942913024/(1x396)
LCM = 119942913024/396
LCM = 302886144
Thus, we can understand that the LCM of 768,836,333,561 is 302886144.
