Given numbers are 984,645,215,439
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 984,645,215,439 is 92874840.
Find LCM of 984,645,215,439 with Prime Factorization
| 3 | 984, 645, 215, 439 |
| 5 | 328, 215, 215, 439 |
| 43 | 328, 43, 43, 439 |
| 328, 1, 1, 439 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 328 x 1 x 1 x 439 = 92874840
Therefore, the lowest common multiple of 984,645,215,439 is 92874840.
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.
984 x 645 x 215 x 439 = 59904271800
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
645 : 1, 3, 5, 15, 43, 129, 215, 645
215 : 1, 5, 43, 215
439 : 1, 439
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,645,215,439, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
645:3x 5x 43
215:5x 43
439:439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 43 = 645
Therefore, the value for common factors is 645.
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 = 59904271800/(1x645)
LCM = 59904271800/645
LCM = 92874840
Thus, we can understand that the LCM of 984,645,215,439 is 92874840.
