So the greatest common factor 56,81,154 is 1.
Lets's calculate LCM of 821,277,117
Given numbers has no common factors except 1. So, there LCM is their product i.e 26607789
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26607789
Therefore, the GCF of Fractions 56/821,81/277,154/117 is 1/26607789
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 821,277,117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,277,117) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,277,117) x common factors =1 x 1 = 1
LCM(821,277,117) = ( 821 × 277 × 117 ) / 1
LCM(821,277,117) = 26607789 / 1
LCM(821,277,117) = 26607789
