Greatest Common Factor
We found the factors 670,788 . The biggest common factor number is the GCF number.
So the greatest common factor 670,788 is 2.
Lets's calculate LCM of 197,162
Given numbers has no common factors except 1. So, there LCM is their product i.e 31914
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/31914
Therefore, the GCF of Fractions 670/197,788/162 is 2/31914
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 197,162 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(197,162) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(197,162) x common factors =1 x 1 = 1
LCM(197,162) = ( 197 × 162 ) / 1
LCM(197,162) = 31914 / 1
LCM(197,162) = 31914
