Greatest Common Factor
We found the factors 42,99,988 . The biggest common factor number is the GCF number.
So the greatest common factor 42,99,988 is 1.
Lets's calculate LCM of 69,71,428
Given numbers has no common factors except 1. So, there LCM is their product i.e 2096772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2096772
Therefore, the GCF of Fractions 42/69,99/71,988/428 is 1/2096772
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 69,71,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,71,428) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(69,71,428) x common factors =1 x 1 = 1
LCM(69,71,428) = ( 69 × 71 × 428 ) / 1
LCM(69,71,428) = 2096772 / 1
LCM(69,71,428) = 2096772
