Given numbers are 484,978,623,561,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,978,623,561,981 is 819669813732.
Find LCM of 484,978,623,561,981 with Prime Factorization
| 2 | 484, 978, 623, 561, 981 |
| 3 | 242, 489, 623, 561, 981 |
| 11 | 242, 163, 623, 187, 327 |
| 22, 163, 623, 17, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 22 x 163 x 623 x 17 x 327 = 819669813732
Therefore, the lowest common multiple of 484,978,623,561,981 is 819669813732.
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.
484 x 978 x 623 x 561 x 981 = 162294623118936
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
978 : 1, 2, 3, 6, 163, 326, 489, 978
623 : 1, 7, 89, 623
561 : 1, 3, 11, 17, 33, 51, 187, 561
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,978,623,561,981, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
978:2x 3x 163
623:7x 89
561:3x 11x 17
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 162294623118936/(1x198)
LCM = 162294623118936/198
LCM = 819669813732
Thus, we can understand that the LCM of 484,978,623,561,981 is 819669813732.
