Given numbers are 388,921,417,983
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,921,417,983 is 48826958676.
Find LCM of 388,921,417,983 with Prime Factorization
| 3 | 388, 921, 417, 983 |
| 388, 307, 139, 983 |
Multiply the prime numbers at the bottom and the left side.
3 x 388 x 307 x 139 x 983 = 48826958676
Therefore, the lowest common multiple of 388,921,417,983 is 48826958676.
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.
388 x 921 x 417 x 983 = 146480876028
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.
388 : 1, 2, 4, 97, 194, 388
921 : 1, 3, 307, 921
417 : 1, 3, 139, 417
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,921,417,983, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
921:3x 307
417:3x 139
983:983
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 146480876028/(1x3)
LCM = 146480876028/3
LCM = 48826958676
Thus, we can understand that the LCM of 388,921,417,983 is 48826958676.
