1,2,3,6,11,22,33,66
Greatest Common Factor
We found the factors 81,76,35,66 . The biggest common factor number is the GCF number.
So the greatest common factor 81,76,35,66 is 1.
Lets's calculate LCM of 97,88,47,31
Given numbers has no common factors except 1. So, there LCM is their product i.e 12436952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12436952
Therefore, the GCF of Fractions 81/97,76/88,35/47,66/31 is 1/12436952
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 97,88,47,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,88,47,31) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,88,47,31) x common factors =1 x 1 = 1
LCM(97,88,47,31) = ( 97 × 88 × 47 × 31 ) / 1
LCM(97,88,47,31) = 12436952 / 1
LCM(97,88,47,31) = 12436952
Here are some samples of GCF of Fractions calculations.
