Given numbers are 871,922,690,713
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,922,690,713 is 8588748090.
Find LCM of 871,922,690,713 with Prime Factorization
| 2 | 871, 922, 690, 713 |
| 23 | 871, 461, 345, 713 |
| 871, 461, 15, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 871 x 461 x 15 x 31 = 8588748090
Therefore, the lowest common multiple of 871,922,690,713 is 8588748090.
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.
871 x 922 x 690 x 713 = 395082412140
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.
871 : 1, 13, 67, 871
922 : 1, 2, 461, 922
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,922,690,713, is 1.
Now, the common factors can be found like this.
871:13x 67
922:2x 461
690:2x 3x 5x 23
713:23x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23 = 46
Therefore, the value for common factors is 46.
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 = 395082412140/(1x46)
LCM = 395082412140/46
LCM = 8588748090
Thus, we can understand that the LCM of 871,922,690,713 is 8588748090.
