Now, list down the factors of 771
:1,3,257,771
Now, list down the factors of 455
:1,5,7,13,35,65,91,455
Greatest Common Factor
We found the factors 771,455 . The biggest common factor number is the GCF number.
So the greatest common factor 771,455 is 1.
Lets's calculate LCM of 48,641
Given numbers has no common factors except 1. So, there LCM is their product i.e 30768
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30768
Therefore, the GCF of Fractions 771/48,455/641 is 1/30768
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 48,641 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,641) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(48,641) x common factors =1 x 1 = 1
LCM(48,641) = ( 48 × 641 ) / 1
LCM(48,641) = 30768 / 1
LCM(48,641) = 30768
