Given numbers are 921,858,871,678,184
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,858,871,678,184 is 183470707992.
Find LCM of 921,858,871,678,184 with Prime Factorization
| 2 | 921, 858, 871, 678, 184 |
| 3 | 921, 429, 871, 339, 92 |
| 13 | 307, 143, 871, 113, 92 |
| 307, 11, 67, 113, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 307 x 11 x 67 x 113 x 92 = 183470707992
Therefore, the lowest common multiple of 921,858,871,678,184 is 183470707992.
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.
921 x 858 x 871 x 678 x 184 = 85864291340256
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.
921 : 1, 3, 307, 921
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
871 : 1, 13, 67, 871
678 : 1, 2, 3, 6, 113, 226, 339, 678
184 : 1, 2, 4, 8, 23, 46, 92, 184
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,858,871,678,184, is 1.
Now, the common factors can be found like this.
921:3x 307
858:2x 3x 11x 13
871:13x 67
678:2x 3x 113
184:2x 2x 2x 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 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 85864291340256/(1x468)
LCM = 85864291340256/468
LCM = 183470707992
Thus, we can understand that the LCM of 921,858,871,678,184 is 183470707992.
