We found the factors 653,1908 . The biggest common factor number is the GCF number.
So the greatest common factor 653,1908 is 1.
Lets's calculate LCM of 890,611
Given numbers has no common factors except 1. So, there LCM is their product i.e 543790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/543790
Therefore, the GCF of Fractions 653/890,1908/611 is 1/543790
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 890,611 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,611) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(890,611) x common factors =1 x 1 = 1
LCM(890,611) = ( 890 × 611 ) / 1
LCM(890,611) = 543790 / 1
LCM(890,611) = 543790
