The LCM of 978,206,660,927 is 33242220.
Find LCM of 978,206,660,927 with Prime Factorization
| 2 | 978, 206, 660, 927 |
| 3 | 489, 103, 330, 927 |
| 103 | 163, 103, 110, 309 |
| 163, 1, 110, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 163 x 1 x 110 x 3 = 33242220
Therefore, the lowest common multiple of 978,206,660,927 is 33242220.
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.
978 x 206 x 660 x 927 = 123262151760
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
206 : 1, 2, 103, 206
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
927 : 1, 3, 9, 103, 309, 927
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,206,660,927, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
206:2x 103
660:2x 2x 3x 5x 11
927:3x 3x 103
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 103 = 3708
Therefore, the value for common factors is 3708.
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 = 123262151760/(1x3708)
LCM = 123262151760/3708
LCM = 33242220
Thus, we can understand that the LCM of 978,206,660,927 is 33242220.
