Greatest Common Factor
We found the factors 43,28,988 . The biggest common factor number is the GCF number.
So the greatest common factor 43,28,988 is 1.
Lets's calculate LCM of 17,12,77
Given numbers has no common factors except 1. So, there LCM is their product i.e 15708
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15708
Therefore, the GCF of Fractions 43/17,28/12,988/77 is 1/15708
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 17,12,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,12,77) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,12,77) x common factors =1 x 1 = 1
LCM(17,12,77) = ( 17 × 12 × 77 ) / 1
LCM(17,12,77) = 15708 / 1
LCM(17,12,77) = 15708
