Given numbers are 424,978,388,923,752
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,978,388,923,752 is 1744921945104.
Find LCM of 424,978,388,923,752 with Prime Factorization
| 2 | 424, 978, 388, 923, 752 |
| 2 | 212, 489, 194, 923, 376 |
| 2 | 106, 489, 97, 923, 188 |
| 53, 489, 97, 923, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 53 x 489 x 97 x 923 x 94 = 1744921945104
Therefore, the lowest common multiple of 424,978,388,923,752 is 1744921945104.
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.
424 x 978 x 388 x 923 x 752 = 111675004486656
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
978 : 1, 2, 3, 6, 163, 326, 489, 978
388 : 1, 2, 4, 97, 194, 388
923 : 1, 13, 71, 923
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,978,388,923,752, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
978:2x 3x 163
388:2x 2x 97
923:13x 71
752:2x 2x 2x 2x 47
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 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 111675004486656/(1x64)
LCM = 111675004486656/64
LCM = 1744921945104
Thus, we can understand that the LCM of 424,978,388,923,752 is 1744921945104.
