Given numbers are 281,920,681,591,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,920,681,591,985 is 34682267640.
Find LCM of 281,920,681,591,985 with Prime Factorization
| 3 | 281, 920, 681, 591, 985 |
| 5 | 281, 920, 227, 197, 985 |
| 197 | 281, 184, 227, 197, 197 |
| 281, 184, 227, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 197 x 281 x 184 x 227 x 1 x 1 = 34682267640
Therefore, the lowest common multiple of 281,920,681,591,985 is 34682267640.
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.
281 x 920 x 681 x 591 x 985 = 102486100876200
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.
281 : 1, 281
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
681 : 1, 3, 227, 681
591 : 1, 3, 197, 591
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,920,681,591,985, is 1.
Now, the common factors can be found like this.
281:281
920:2x 2x 2x 5x 23
681:3x 227
591:3x 197
985:5x 197
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 197 = 2955
Therefore, the value for common factors is 2955.
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 = 102486100876200/(1x2955)
LCM = 102486100876200/2955
LCM = 34682267640
Thus, we can understand that the LCM of 281,920,681,591,985 is 34682267640.
