Given numbers are 171,627,781,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,627,781,923 is 1736163.
Find LCM of 171,627,781,923 with Prime Factorization
| 3 | 171, 627, 781, 923 |
| 11 | 57, 209, 781, 923 |
| 19 | 57, 19, 71, 923 |
| 71 | 3, 1, 71, 923 |
| 3, 1, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 71 x 3 x 1 x 1 x 13 = 1736163
Therefore, the lowest common multiple of 171,627,781,923 is 1736163.
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.
171 x 627 x 781 x 923 = 77288768271
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.
171 : 1, 3, 9, 19, 57, 171
627 : 1, 3, 11, 19, 33, 57, 209, 627
781 : 1, 11, 71, 781
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,627,781,923, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
627:3x 11x 19
781:11x 71
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19x 71 = 44517
Therefore, the value for common factors is 44517.
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 = 77288768271/(1x44517)
LCM = 77288768271/44517
LCM = 1736163
Thus, we can understand that the LCM of 171,627,781,923 is 1736163.
