Lets's calculate LCM of 777,190
Given numbers has no common factors except 1. So, there LCM is their product i.e 147630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/147630
Therefore, the GCF of Fractions 918/777,630/190 is 18/147630
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 777,190 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(777,190) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(777,190) x common factors =1 x 1 = 1
LCM(777,190) = ( 777 × 190 ) / 1
LCM(777,190) = 147630 / 1
LCM(777,190) = 147630
