Therefore, the GCF of 81/865,36/3004 is 9/2598460.
To find the highest common factor of 81,36, we have to find the factors of both numbers and list the highest common factor.
The factors of 81 are 1, 3, 9, 27, 81
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
The HCF of 81,36 is 9.
Lets's calculate GCF of 81,36
3 | 81, 36 |
3 | 27, 12 |
9, 4 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 81
:1,3,9,27,81
Now, list down the factors of 36
:1,2,3,4,6,9,12,18,36
Greatest Common Factor
We found the factors 81,36 . The biggest common factor number is the GCF number.
So the greatest common factor 81,36 is 9.
Lets's calculate LCM of 865,3004
Given numbers has no common factors except 1. So, there LCM is their product i.e 2598460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/2598460
Therefore, the GCF of Fractions 81/865,36/3004 is 9/2598460
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 865,3004 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(865,3004) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(865,3004) x common factors =1 x 1 = 1
LCM(865,3004) = ( 865 × 3004 ) / 1
LCM(865,3004) = 2598460 / 1
LCM(865,3004) = 2598460
