Given numbers are 389,216,656,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,216,656,591 is 1357323696.
Find LCM of 389,216,656,591 with Prime Factorization
2 | 389, 216, 656, 591 |
2 | 389, 108, 328, 591 |
2 | 389, 54, 164, 591 |
3 | 389, 27, 82, 591 |
389, 9, 82, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 389 x 9 x 82 x 197 = 1357323696
Therefore, the lowest common multiple of 389,216,656,591 is 1357323696.
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.
389 x 216 x 656 x 591 = 32575768704
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.
389 : 1, 389
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,216,656,591, is 1.
Now, the common factors can be found like this.
389:389
216:2x 2x 2x 3x 3x 3
656:2x 2x 2x 2x 41
591:3x 197
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 3 = 24
Therefore, the value for common factors is 24.
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 = 32575768704/(1x24)
LCM = 32575768704/24
LCM = 1357323696
Thus, we can understand that the LCM of 389,216,656,591 is 1357323696.
