Given numbers are 311,622,991,341,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,622,991,341,605 is 11560619510.
Find LCM of 311,622,991,341,605 with Prime Factorization
| 11 | 311, 622, 991, 341, 605 |
| 311 | 311, 622, 991, 31, 55 |
| 1, 2, 991, 31, 55 |
Multiply the prime numbers at the bottom and the left side.
11 x 311 x 1 x 2 x 991 x 31 x 55 = 11560619510
Therefore, the lowest common multiple of 311,622,991,341,605 is 11560619510.
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 622 x 991 x 341 x 605 = 39548879343710
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
622 : 1, 2, 311, 622
991 : 1, 991
341 : 1, 11, 31, 341
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,622,991,341,605, is 1.
Now, the common factors can be found like this.
311:311
622:2x 311
991:991
341:11x 31
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 311 = 3421
Therefore, the value for common factors is 3421.
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 = 39548879343710/(1x3421)
LCM = 39548879343710/3421
LCM = 11560619510
Thus, we can understand that the LCM of 311,622,991,341,605 is 11560619510.
