Given numbers are 205,538,706,984,142
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,538,706,984,142 is 33170379240.
Find LCM of 205,538,706,984,142 with Prime Factorization
| 2 | 205, 538, 706, 984, 142 |
| 41 | 205, 269, 353, 492, 71 |
| 5, 269, 353, 12, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 5 x 269 x 353 x 12 x 71 = 33170379240
Therefore, the lowest common multiple of 205,538,706,984,142 is 33170379240.
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.
205 x 538 x 706 x 984 x 142 = 10879884390720
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.
205 : 1, 5, 41, 205
538 : 1, 2, 269, 538
706 : 1, 2, 353, 706
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,538,706,984,142, is 1.
Now, the common factors can be found like this.
205:5x 41
538:2x 269
706:2x 353
984:2x 2x 2x 3x 41
142:2x 71
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 41 = 328
Therefore, the value for common factors is 328.
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 = 10879884390720/(1x328)
LCM = 10879884390720/328
LCM = 33170379240
Thus, we can understand that the LCM of 205,538,706,984,142 is 33170379240.
