Given numbers are 786,988,966,627,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,988,966,627,978 is 112087107132.
Find LCM of 786,988,966,627,978 with Prime Factorization
| 2 | 786, 988, 966, 627, 978 |
| 3 | 393, 494, 483, 627, 489 |
| 19 | 131, 494, 161, 209, 163 |
| 131, 26, 161, 11, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 131 x 26 x 161 x 11 x 163 = 112087107132
Therefore, the lowest common multiple of 786,988,966,627,978 is 112087107132.
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.
786 x 988 x 966 x 627 x 978 = 460005487669728
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
627 : 1, 3, 11, 19, 33, 57, 209, 627
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,988,966,627,978, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
988:2x 2x 13x 19
966:2x 3x 7x 23
627:3x 11x 19
978:2x 3x 163
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 3x 3x 19 = 4104
Therefore, the value for common factors is 4104.
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 = 460005487669728/(1x4104)
LCM = 460005487669728/4104
LCM = 112087107132
Thus, we can understand that the LCM of 786,988,966,627,978 is 112087107132.
