Given numbers are 128,103,899,930,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,103,899,930,278 is 24712287360.
Find LCM of 128,103,899,930,278 with Prime Factorization
| 2 | 128, 103, 899, 930, 278 |
| 31 | 64, 103, 899, 465, 139 |
| 64, 103, 29, 15, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 64 x 103 x 29 x 15 x 139 = 24712287360
Therefore, the lowest common multiple of 128,103,899,930,278 is 24712287360.
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.
128 x 103 x 899 x 930 x 278 = 3064323632640
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
103 : 1, 103
899 : 1, 29, 31, 899
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,103,899,930,278, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
103:103
899:29x 31
930:2x 3x 5x 31
278:2x 139
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 31 = 124
Therefore, the value for common factors is 124.
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 = 3064323632640/(1x124)
LCM = 3064323632640/124
LCM = 24712287360
Thus, we can understand that the LCM of 128,103,899,930,278 is 24712287360.
