Lets's calculate LCM of 520,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 409240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/409240
Therefore, the GCF of Fractions 516/520,1958/787 is 2/409240
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 520,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(520,787) x common factors =1 x 1 = 1
LCM(520,787) = ( 520 × 787 ) / 1
LCM(520,787) = 409240 / 1
LCM(520,787) = 409240
