So the greatest common factor 120,7124 is 4.
Lets's calculate LCM of 644,2675
Given numbers has no common factors except 1. So, there LCM is their product i.e 1722700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1722700
Therefore, the GCF of Fractions 120/644,7124/2675 is 4/1722700
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 644,2675 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,2675) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(644,2675) x common factors =1 x 1 = 1
LCM(644,2675) = ( 644 × 2675 ) / 1
LCM(644,2675) = 1722700 / 1
LCM(644,2675) = 1722700
