Lets's calculate LCM of 38,2635
Given numbers has no common factors except 1. So, there LCM is their product i.e 100130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/100130
Therefore, the GCF of Fractions 858/38,688/2635 is 2/100130
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 38,2635 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,2635) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(38,2635) x common factors =1 x 1 = 1
LCM(38,2635) = ( 38 × 2635 ) / 1
LCM(38,2635) = 100130 / 1
LCM(38,2635) = 100130
