Given numbers are 8151,7755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8151,7755 is 1915485.
Find LCM of 8151,7755 with Prime Factorization
| 3 | 8151, 7755 |
| 11 | 2717, 2585 |
| 247, 235 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 247 x 235 = 1915485
Therefore, the lowest common multiple of 8151,7755 is 1915485.
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.
8151 x 7755 = 63211005
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.
8151 : 1, 3, 11, 13, 19, 33, 39, 57, 143, 209, 247, 429, 627, 741, 2717, 8151
7755 : 1, 3, 5, 11, 15, 33, 47, 55, 141, 165, 235, 517, 705, 1551, 2585, 7755
33 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8151,7755, is 33.
Now, the common factors can be found like this.
8151:3x 11x 13x 19
7755:3x 5x 11x 47
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 = 63211005/(33x1)
LCM = 63211005/33
LCM = 1915485
Thus, we can understand that the LCM of 8151,7755 is 1915485.
