Greatest Common Factor
We found the factors 7781,7431 . The biggest common factor number is the GCF number.
So the greatest common factor 7781,7431 is 1.
Lets's calculate LCM of 280,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 277480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/277480
Therefore, the GCF of Fractions 7781/280,7431/991 is 1/277480
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 280,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(280,991) x common factors =1 x 1 = 1
LCM(280,991) = ( 280 × 991 ) / 1
LCM(280,991) = 277480 / 1
LCM(280,991) = 277480
