Lets's calculate LCM of 771,128
Given numbers has no common factors except 1. So, there LCM is their product i.e 98688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/98688
Therefore, the GCF of Fractions 285/771,708/128 is 3/98688
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 771,128 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(771,128) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(771,128) x common factors =1 x 1 = 1
LCM(771,128) = ( 771 × 128 ) / 1
LCM(771,128) = 98688 / 1
LCM(771,128) = 98688
