Lets's calculate LCM of 242,5217
Given numbers has no common factors except 1. So, there LCM is their product i.e 1262514
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1262514
Therefore, the GCF of Fractions 72/242,1161/5217 is 9/1262514
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 242,5217 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(242,5217) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(242,5217) x common factors =1 x 1 = 1
LCM(242,5217) = ( 242 × 5217 ) / 1
LCM(242,5217) = 1262514 / 1
LCM(242,5217) = 1262514
