Given numbers are 788,197,729,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,197,729,939 is 179803476.
Find LCM of 788,197,729,939 with Prime Factorization
3 | 788, 197, 729, 939 |
197 | 788, 197, 243, 313 |
4, 1, 243, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 197 x 4 x 1 x 243 x 313 = 179803476
Therefore, the lowest common multiple of 788,197,729,939 is 179803476.
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 197 x 729 x 939 = 106263854316
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
197 : 1, 197
729 : 1, 3, 9, 27, 81, 243, 729
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,197,729,939, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
197:197
729:3x 3x 3x 3x 3x 3
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 197 = 591
Therefore, the value for common factors is 591.
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 = 106263854316/(1x591)
LCM = 106263854316/591
LCM = 179803476
Thus, we can understand that the LCM of 788,197,729,939 is 179803476.
