∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 259
:1,7,37,259
Now, list down the factors of 749
:1,7,107,749
Greatest Common Factor
We found the factors 259,749 . The biggest common factor number is the GCF number.
So the greatest common factor 259,749 is 7.
Lets's calculate LCM of 63,1985
Given numbers has no common factors except 1. So, there LCM is their product i.e 125055
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/125055
Therefore, the GCF of Fractions 259/63,749/1985 is 7/125055
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 63,1985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,1985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(63,1985) x common factors =1 x 1 = 1
LCM(63,1985) = ( 63 × 1985 ) / 1
LCM(63,1985) = 125055 / 1
LCM(63,1985) = 125055
