Given numbers are 927,721,389,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 927,721,389,138 is 116114166.
Find LCM of 927,721,389,138 with Prime Factorization
| 3 | 927, 721, 389, 138 |
| 103 | 309, 721, 389, 46 |
| 3, 7, 389, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 3 x 7 x 389 x 46 = 116114166
Therefore, the lowest common multiple of 927,721,389,138 is 116114166.
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.
927 x 721 x 389 x 138 = 35879277294
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.
927 : 1, 3, 9, 103, 309, 927
721 : 1, 7, 103, 721
389 : 1, 389
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 927,721,389,138, is 1.
Now, the common factors can be found like this.
927:3x 3x 103
721:7x 103
389:389
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 103 = 309
Therefore, the value for common factors is 309.
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 = 35879277294/(1x309)
LCM = 35879277294/309
LCM = 116114166
Thus, we can understand that the LCM of 927,721,389,138 is 116114166.
