The HCF of 87,15,261 is 3.
Lets's calculate GCF of 87,15,261
3 | 87, 15, 261 |
29, 5, 87 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 87
:1,3,29,87
Now, list down the factors of 15
:1,3,5,15
Now, list down the factors of 261
:1,3,9,29,87,261
Greatest Common Factor
We found the factors 87,15,261 . The biggest common factor number is the GCF number.
So the greatest common factor 87,15,261 is 3.
Lets's calculate LCM of 88,36,64
2 | 88, 36, 64 |
2 | 44, 18, 32 |
2 | 22, 9, 16 |
11, 9, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 9 x 8 = 6336
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6336
Therefore, the GCF of Fractions 87/88,15/36,261/64 is 3/6336
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 88,36,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,36,64) = 4
common factors(in case of two or more numbers have common factors) = 8
GCF(88,36,64) x common factors =4 x 8 = 32
LCM(88,36,64) = ( 88 × 36 × 64 ) / 32
LCM(88,36,64) = 202752 / 32
LCM(88,36,64) = 6336
