Given numbers are 788,394,163,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,394,163,447 is 57414468.
Find LCM of 788,394,163,447 with Prime Factorization
| 2 | 788, 394, 163, 447 |
| 197 | 394, 197, 163, 447 |
| 2, 1, 163, 447 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 2 x 1 x 163 x 447 = 57414468
Therefore, the lowest common multiple of 788,394,163,447 is 57414468.
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 394 x 163 x 447 = 22621300392
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
394 : 1, 2, 197, 394
163 : 1, 163
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,394,163,447, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
394:2x 197
163:163
447:3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 197 = 394
Therefore, the value for common factors is 394.
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 = 22621300392/(1x394)
LCM = 22621300392/394
LCM = 57414468
Thus, we can understand that the LCM of 788,394,163,447 is 57414468.
