Given numbers are 311,139,871,121,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,139,871,121,715 is 22779737695.
Find LCM of 311,139,871,121,715 with Prime Factorization
| 11 | 311, 139, 871, 121, 715 |
| 13 | 311, 139, 871, 11, 65 |
| 311, 139, 67, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 311 x 139 x 67 x 11 x 5 = 22779737695
Therefore, the lowest common multiple of 311,139,871,121,715 is 22779737695.
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.
311 x 139 x 871 x 121 x 715 = 3257502490385
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.
311 : 1, 311
139 : 1, 139
871 : 1, 13, 67, 871
121 : 1, 11, 121
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,139,871,121,715, is 1.
Now, the common factors can be found like this.
311:311
139:139
871:13x 67
121:11x 11
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 3257502490385/(1x143)
LCM = 3257502490385/143
LCM = 22779737695
Thus, we can understand that the LCM of 311,139,871,121,715 is 22779737695.
