:1,3,9,17,27,51,153,459
Greatest Common Factor
We found the factors 340,459 . The biggest common factor number is the GCF number.
So the greatest common factor 340,459 is 17.
Lets's calculate LCM of 842,755
Given numbers has no common factors except 1. So, there LCM is their product i.e 635710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/635710
Therefore, the GCF of Fractions 340/842,459/755 is 17/635710
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 842,755 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(842,755) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(842,755) x common factors =1 x 1 = 1
LCM(842,755) = ( 842 × 755 ) / 1
LCM(842,755) = 635710 / 1
LCM(842,755) = 635710
