Greatest Common Factor
We found the factors 86,54,26,42 . The biggest common factor number is the GCF number.
So the greatest common factor 86,54,26,42 is 2.
Lets's calculate LCM of 14,79,31,97
Given numbers has no common factors except 1. So, there LCM is their product i.e 3325742
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3325742
Therefore, the GCF of Fractions 86/14,54/79,26/31,42/97 is 2/3325742
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 14,79,31,97 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,79,31,97) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(14,79,31,97) x common factors =1 x 1 = 1
LCM(14,79,31,97) = ( 14 × 79 × 31 × 97 ) / 1
LCM(14,79,31,97) = 3325742 / 1
LCM(14,79,31,97) = 3325742
