Given numbers are 3,998,865,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3,998,865,381 is 328905870.
Find LCM of 3,998,865,381 with Prime Factorization
3 | 3, 998, 865, 381 |
1, 998, 865, 127 |
Multiply the prime numbers at the bottom and the left side.
3 x 1 x 998 x 865 x 127 = 328905870
Therefore, the lowest common multiple of 3,998,865,381 is 328905870.
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.
3 x 998 x 865 x 381 = 986717610
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.
3 : 1, 3
998 : 1, 2, 499, 998
865 : 1, 5, 173, 865
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,998,865,381, is 1.
Now, the common factors can be found like this.
3:3
998:2x 499
865:5x 173
381:3x 127
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 = 986717610/(1x3)
LCM = 986717610/3
LCM = 328905870
Thus, we can understand that the LCM of 3,998,865,381 is 328905870.
