Given numbers are 788,788,261,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,788,261,145 is 1028340.
Find LCM of 788,788,261,145 with Prime Factorization
| 2 | 788, 788, 261, 145 |
| 2 | 394, 394, 261, 145 |
| 29 | 197, 197, 261, 145 |
| 197 | 197, 197, 9, 5 |
| 1, 1, 9, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 197 x 1 x 1 x 9 x 5 = 1028340
Therefore, the lowest common multiple of 788,788,261,145 is 1028340.
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.
788 x 788 x 261 x 145 = 23499625680
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.
788 : 1, 2, 4, 197, 394, 788
788 : 1, 2, 4, 197, 394, 788
261 : 1, 3, 9, 29, 87, 261
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,788,261,145, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
788:2x 2x 197
261:3x 3x 29
145:5x 29
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 29x 197 = 22852
Therefore, the value for common factors is 22852.
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 = 23499625680/(1x22852)
LCM = 23499625680/22852
LCM = 1028340
Thus, we can understand that the LCM of 788,788,261,145 is 1028340.
