Greatest Common Factor
We found the factors 315,4998 . The biggest common factor number is the GCF number.
So the greatest common factor 315,4998 is 21.
Lets's calculate LCM of 67,170
Given numbers has no common factors except 1. So, there LCM is their product i.e 11390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/11390
Therefore, the GCF of Fractions 315/67,4998/170 is 21/11390
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 67,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,170) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,170) x common factors =1 x 1 = 1
LCM(67,170) = ( 67 × 170 ) / 1
LCM(67,170) = 11390 / 1
LCM(67,170) = 11390
