So the greatest common factor 684,223 is 1.
Lets's calculate LCM of 980,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 647780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/647780
Therefore, the GCF of Fractions 684/980,223/661 is 1/647780
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 980,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(980,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(980,661) x common factors =1 x 1 = 1
LCM(980,661) = ( 980 × 661 ) / 1
LCM(980,661) = 647780 / 1
LCM(980,661) = 647780
