The factors of 89 are 1, 89
The factors of 89 are 1, 89
The HCF of 89,89 is 89.
Lets's calculate GCF of 89,89
89 | 89, 89 |
1, 1 |
∴ So the GCF of the given numbers is 89 = 89
Lets's calculate LCM of 261,7170
3 | 261, 7170 |
87, 2390 |
∴ So the LCM of the given numbers is 3 x 87 x 2390 = 623790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 89/623790
Therefore, the GCF of Fractions 89/261,89/7170 is 89/623790
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 261,7170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(261,7170) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(261,7170) x common factors =3 x 1 = 3
LCM(261,7170) = ( 261 × 7170 ) / 3
LCM(261,7170) = 1871370 / 3
LCM(261,7170) = 623790
