Therefore, the GCF of 81/764,67/1649 is 1/1259836.
To find the highest common factor of 81,67, 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 67 are 1, 67
The HCF of 81,67 is 1.
Lets's calculate GCF of 81,67
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 764,1649
Given numbers has no common factors except 1. So, there LCM is their product i.e 1259836
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1259836
Therefore, the GCF of Fractions 81/764,67/1649 is 1/1259836
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 764,1649 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(764,1649) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(764,1649) x common factors =1 x 1 = 1
LCM(764,1649) = ( 764 × 1649 ) / 1
LCM(764,1649) = 1259836 / 1
LCM(764,1649) = 1259836
