The LCM of 208,741,728,786 is 10871952.
Find LCM of 208,741,728,786 with Prime Factorization
| 2 | 208, 741, 728, 786 |
| 2 | 104, 741, 364, 393 |
| 2 | 52, 741, 182, 393 |
| 3 | 26, 741, 91, 393 |
| 13 | 26, 247, 91, 131 |
| 2, 19, 7, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 2 x 19 x 7 x 131 = 10871952
Therefore, the lowest common multiple of 208,741,728,786 is 10871952.
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.
208 x 741 x 728 x 786 = 88193274624
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
741 : 1, 3, 13, 19, 39, 57, 247, 741
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,741,728,786, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
741:3x 13x 19
728:2x 2x 2x 7x 13
786:2x 3x 131
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 3x 13x 13 = 8112
Therefore, the value for common factors is 8112.
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 = 88193274624/(1x8112)
LCM = 88193274624/8112
LCM = 10871952
Thus, we can understand that the LCM of 208,741,728,786 is 10871952.
