Find LCM of 978,981,815,416,464 with Prime Factorization
| 2 | 978, 981, 815, 416, 464 |
| 2 | 489, 981, 815, 208, 232 |
| 2 | 489, 981, 815, 104, 116 |
| 2 | 489, 981, 815, 52, 58 |
| 3 | 489, 981, 815, 26, 29 |
| 163 | 163, 327, 815, 26, 29 |
| 1, 327, 5, 26, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 163 x 1 x 327 x 5 x 26 x 29 = 9645348960
Therefore, the lowest common multiple of 978,981,815,416,464 is 9645348960.
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 981 x 815 x 416 x 464 = 150930420526080
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
981 : 1, 3, 9, 109, 327, 981
815 : 1, 5, 163, 815
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,981,815,416,464, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
981:3x 3x 109
815:5x 163
416:2x 2x 2x 2x 2x 13
464:2x 2x 2x 2x 29
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 163 = 15648
Therefore, the value for common factors is 15648.
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 = 150930420526080/(1x15648)
LCM = 150930420526080/15648
LCM = 9645348960
Thus, we can understand that the LCM of 978,981,815,416,464 is 9645348960.
