Given numbers are 861,871,369,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,871,369,197 is 443209221.
Find LCM of 861,871,369,197 with Prime Factorization
| 3 | 861, 871, 369, 197 |
| 41 | 287, 871, 123, 197 |
| 7, 871, 3, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 7 x 871 x 3 x 197 = 443209221
Therefore, the lowest common multiple of 861,871,369,197 is 443209221.
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.
861 x 871 x 369 x 197 = 54514734183
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
871 : 1, 13, 67, 871
369 : 1, 3, 9, 41, 123, 369
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,871,369,197, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
871:13x 67
369:3x 3x 41
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 54514734183/(1x123)
LCM = 54514734183/123
LCM = 443209221
Thus, we can understand that the LCM of 861,871,369,197 is 443209221.
