:1,2,4,5,10,11,20,22,44,55,110,220
Greatest Common Factor
We found the factors 812,220 . The biggest common factor number is the GCF number.
So the greatest common factor 812,220 is 4.
Lets's calculate LCM of 167,405
Given numbers has no common factors except 1. So, there LCM is their product i.e 67635
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/67635
Therefore, the GCF of Fractions 812/167,220/405 is 4/67635
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 167,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(167,405) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(167,405) x common factors =1 x 1 = 1
LCM(167,405) = ( 167 × 405 ) / 1
LCM(167,405) = 67635 / 1
LCM(167,405) = 67635
