Given numbers are 740,871,871,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,871,871,481 is 644540.
Find LCM of 740,871,871,481 with Prime Factorization
| 13 | 740, 871, 871, 481 |
| 37 | 740, 67, 67, 37 |
| 67 | 20, 67, 67, 1 |
| 20, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 37 x 67 x 20 x 1 x 1 x 1 = 644540
Therefore, the lowest common multiple of 740,871,871,481 is 644540.
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.
740 x 871 x 871 x 481 = 270030677540
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
871 : 1, 13, 67, 871
871 : 1, 13, 67, 871
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,871,871,481, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
871:13x 67
871:13x 67
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13x 37x 67 = 418951
Therefore, the value for common factors is 418951.
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 = 270030677540/(1x418951)
LCM = 270030677540/418951
LCM = 644540
Thus, we can understand that the LCM of 740,871,871,481 is 644540.
