Given numbers are 978,484,489,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,484,489,786 is 31004556.
Find LCM of 978,484,489,786 with Prime Factorization
| 2 | 978, 484, 489, 786 |
| 3 | 489, 242, 489, 393 |
| 163 | 163, 242, 163, 131 |
| 1, 242, 1, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 242 x 1 x 131 = 31004556
Therefore, the lowest common multiple of 978,484,489,786 is 31004556.
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 484 x 489 x 786 = 181934734608
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
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
489 : 1, 3, 163, 489
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 978,484,489,786, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
484:2x 2x 11x 11
489:3x 163
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 3x 3x 163 = 5868
Therefore, the value for common factors is 5868.
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 = 181934734608/(1x5868)
LCM = 181934734608/5868
LCM = 31004556
Thus, we can understand that the LCM of 978,484,489,786 is 31004556.
