So the greatest common factor 644,928 is 4.
Lets's calculate LCM of 602,201
Given numbers has no common factors except 1. So, there LCM is their product i.e 121002
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/121002
Therefore, the GCF of Fractions 644/602,928/201 is 4/121002
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 602,201 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(602,201) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(602,201) x common factors =1 x 1 = 1
LCM(602,201) = ( 602 × 201 ) / 1
LCM(602,201) = 121002 / 1
LCM(602,201) = 121002
