:1,2,29,31,58,62,899,1798
Greatest Common Factor
We found the factors 1643,1798 . The biggest common factor number is the GCF number.
So the greatest common factor 1643,1798 is 31.
Lets's calculate LCM of 751,211
Given numbers has no common factors except 1. So, there LCM is their product i.e 158461
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/158461
Therefore, the GCF of Fractions 1643/751,1798/211 is 31/158461
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 751,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(751,211) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(751,211) x common factors =1 x 1 = 1
LCM(751,211) = ( 751 × 211 ) / 1
LCM(751,211) = 158461 / 1
LCM(751,211) = 158461
