Find LCM of 206,646,981,654,782 with Prime Factorization
| 2 | 206, 646, 981, 654, 782 |
| 3 | 103, 323, 981, 327, 391 |
| 17 | 103, 323, 109, 327, 391 |
| 109 | 103, 19, 109, 327, 23 |
| 103, 19, 1, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 109 x 103 x 19 x 1 x 3 x 23 = 1501296894
Therefore, the lowest common multiple of 206,646,981,654,782 is 1501296894.
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.
206 x 646 x 981 x 654 x 782 = 66765675469968
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.
206 : 1, 2, 103, 206
646 : 1, 2, 17, 19, 34, 38, 323, 646
981 : 1, 3, 9, 109, 327, 981
654 : 1, 2, 3, 6, 109, 218, 327, 654
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,646,981,654,782, is 1.
Now, the common factors can be found like this.
206:2x 103
646:2x 17x 19
981:3x 3x 109
654:2x 3x 109
782:2x 17x 23
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 17x 109 = 44472
Therefore, the value for common factors is 44472.
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 = 66765675469968/(1x44472)
LCM = 66765675469968/44472
LCM = 1501296894
Thus, we can understand that the LCM of 206,646,981,654,782 is 1501296894.
