So the greatest common factor 576,639 is 9.
Lets's calculate LCM of 97,2221
Given numbers has no common factors except 1. So, there LCM is their product i.e 215437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/215437
Therefore, the GCF of Fractions 576/97,639/2221 is 9/215437
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 97,2221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,2221) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,2221) x common factors =1 x 1 = 1
LCM(97,2221) = ( 97 × 2221 ) / 1
LCM(97,2221) = 215437 / 1
LCM(97,2221) = 215437
