So the greatest common factor 697,315 is 1.
Lets's calculate LCM of 643,164
Given numbers has no common factors except 1. So, there LCM is their product i.e 105452
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/105452
Therefore, the GCF of Fractions 697/643,315/164 is 1/105452
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 643,164 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,164) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,164) x common factors =1 x 1 = 1
LCM(643,164) = ( 643 × 164 ) / 1
LCM(643,164) = 105452 / 1
LCM(643,164) = 105452
