Lets's calculate LCM of 665,137
Given numbers has no common factors except 1. So, there LCM is their product i.e 91105
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/91105
Therefore, the GCF of Fractions 897/665,636/137 is 3/91105
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 665,137 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(665,137) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(665,137) x common factors =1 x 1 = 1
LCM(665,137) = ( 665 × 137 ) / 1
LCM(665,137) = 91105 / 1
LCM(665,137) = 91105
