The LCM of 861,791,187,957,196 is 14773358292.
Find LCM of 861,791,187,957,196 with Prime Factorization
| 3 | 861, 791, 187, 957, 196 |
| 7 | 287, 791, 187, 319, 196 |
| 11 | 41, 113, 187, 319, 28 |
| 41, 113, 17, 29, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 41 x 113 x 17 x 29 x 28 = 14773358292
Therefore, the lowest common multiple of 861,791,187,957,196 is 14773358292.
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 791 x 187 x 957 x 196 = 23888520358164
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
791 : 1, 7, 113, 791
187 : 1, 11, 17, 187
957 : 1, 3, 11, 29, 33, 87, 319, 957
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,791,187,957,196, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
791:7x 113
187:11x 17
957:3x 11x 29
196:2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11 = 1617
Therefore, the value for common factors is 1617.
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 = 23888520358164/(1x1617)
LCM = 23888520358164/1617
LCM = 14773358292
Thus, we can understand that the LCM of 861,791,187,957,196 is 14773358292.
