Given numbers are 918,871,338,640,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 918,871,338,640,923 is 236163358080.
Find LCM of 918,871,338,640,923 with Prime Factorization
| 2 | 918, 871, 338, 640, 923 |
| 13 | 459, 871, 169, 320, 923 |
| 459, 67, 13, 320, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 459 x 67 x 13 x 320 x 71 = 236163358080
Therefore, the lowest common multiple of 918,871,338,640,923 is 236163358080.
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.
918 x 871 x 338 x 640 x 923 = 159646430062080
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
871 : 1, 13, 67, 871
338 : 1, 2, 13, 26, 169, 338
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,871,338,640,923, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
871:13x 67
338:2x 13x 13
640:2x 2x 2x 2x 2x 2x 2x 5
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.
2x 2x 13x 13 = 676
Therefore, the value for common factors is 676.
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 = 159646430062080/(1x676)
LCM = 159646430062080/676
LCM = 236163358080
Thus, we can understand that the LCM of 918,871,338,640,923 is 236163358080.
