Given numbers are 206,772,374,805,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 206,772,374,805,161 is 11969941060.
Find LCM of 206,772,374,805,161 with Prime Factorization
| 2 | 206, 772, 374, 805, 161 |
| 7 | 103, 386, 187, 805, 161 |
| 23 | 103, 386, 187, 115, 23 |
| 103, 386, 187, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 103 x 386 x 187 x 5 x 1 = 11969941060
Therefore, the lowest common multiple of 206,772,374,805,161 is 11969941060.
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.
206 x 772 x 374 x 805 x 161 = 7708642042640
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.
206 : 1, 2, 103, 206
772 : 1, 2, 4, 193, 386, 772
374 : 1, 2, 11, 17, 22, 34, 187, 374
805 : 1, 5, 7, 23, 35, 115, 161, 805
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,772,374,805,161, is 1.
Now, the common factors can be found like this.
206:2x 103
772:2x 2x 193
374:2x 11x 17
805:5x 7x 23
161:7x 23
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 7x 23 = 644
Therefore, the value for common factors is 644.
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 = 7708642042640/(1x644)
LCM = 7708642042640/644
LCM = 11969941060
Thus, we can understand that the LCM of 206,772,374,805,161 is 11969941060.
