Given numbers are 7881,1647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7881,1647 is 4326669.
Find LCM of 7881,1647 with Prime Factorization
| 3 | 7881, 1647 |
| 2627, 549 |
Multiply the prime numbers at the bottom and the left side.
3 x 2627 x 549 = 4326669
Therefore, the lowest common multiple of 7881,1647 is 4326669.
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.
7881 x 1647 = 12980007
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.
7881 : 1, 3, 37, 71, 111, 213, 2627, 7881
1647 : 1, 3, 9, 27, 61, 183, 549, 1647
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7881,1647, is 3.
Now, the common factors can be found like this.
7881:3x 37x 71
1647:3x 3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 12980007/(3x1)
LCM = 12980007/3
LCM = 4326669
Thus, we can understand that the LCM of 7881,1647 is 4326669.
