The greatest common factor of 181/77,154/155 = [GCF of 181,154]/[LCM of 77,155]= 1/11935
Therefore, the GCF of 181/77,154/155 is 1/11935.
To find the highest common factor of 181,154, we have to find the factors of both numbers and list the highest common factor.
The factors of 181 are 1, 181
The factors of 154 are 1, 2, 7, 11, 14, 22, 77, 154
The HCF of 181,154 is 1.
Lets's calculate GCF of 181,154
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 181
:1,181
Now, list down the factors of 154
:1,2,7,11,14,22,77,154
Greatest Common Factor
We found the factors 181,154 . The biggest common factor number is the GCF number.
So the greatest common factor 181,154 is 1.
Lets's calculate LCM of 77,155
Given numbers has no common factors except 1. So, there LCM is their product i.e 11935
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11935
Therefore, the GCF of Fractions 181/77,154/155 is 1/11935
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 77,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,155) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,155) x common factors =1 x 1 = 1
LCM(77,155) = ( 77 × 155 ) / 1
LCM(77,155) = 11935 / 1
LCM(77,155) = 11935
