Now, list down the factors of 978
:1,2,3,6,163,326,489,978
Now, list down the factors of 955
:1,5,191,955
Greatest Common Factor
We found the factors 978,955 . The biggest common factor number is the GCF number.
So the greatest common factor 978,955 is 1.
Lets's calculate LCM of 31,256
Given numbers has no common factors except 1. So, there LCM is their product i.e 7936
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7936
Therefore, the GCF of Fractions 978/31,955/256 is 1/7936
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 31,256 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,256) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,256) x common factors =1 x 1 = 1
LCM(31,256) = ( 31 × 256 ) / 1
LCM(31,256) = 7936 / 1
LCM(31,256) = 7936
