Greatest Common Factor
We found the factors 228,857,558 . The biggest common factor number is the GCF number.
So the greatest common factor 228,857,558 is 1.
Lets's calculate LCM of 43,42,65
Given numbers has no common factors except 1. So, there LCM is their product i.e 117390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/117390
Therefore, the GCF of Fractions 228/43,857/42,558/65 is 1/117390
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 43,42,65 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(43,42,65) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(43,42,65) x common factors =1 x 1 = 1
LCM(43,42,65) = ( 43 × 42 × 65 ) / 1
LCM(43,42,65) = 117390 / 1
LCM(43,42,65) = 117390
