Lets's calculate GCF of 96,77,21
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 96
:1,2,3,4,6,8,12,16,24,32,48,96
Now, list down the factors of 77
:1,7,11,77
Now, list down the factors of 21
:1,3,7,21
Greatest Common Factor
We found the factors 96,77,21 . The biggest common factor number is the GCF number.
So the greatest common factor 96,77,21 is 1.
Lets's calculate LCM of 17,47,503
Given numbers has no common factors except 1. So, there LCM is their product i.e 401897
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/401897
Therefore, the GCF of Fractions 96/17,77/47,21/503 is 1/401897
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 17,47,503 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,47,503) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,47,503) x common factors =1 x 1 = 1
LCM(17,47,503) = ( 17 × 47 × 503 ) / 1
LCM(17,47,503) = 401897 / 1
LCM(17,47,503) = 401897
