:1,5,31,155
Greatest Common Factor
We found the factors 768,155 . The biggest common factor number is the GCF number.
So the greatest common factor 768,155 is 1.
Lets's calculate LCM of 70,243
Given numbers has no common factors except 1. So, there LCM is their product i.e 17010
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17010
Therefore, the GCF of Fractions 768/70,155/243 is 1/17010
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 70,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,243) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(70,243) x common factors =1 x 1 = 1
LCM(70,243) = ( 70 × 243 ) / 1
LCM(70,243) = 17010 / 1
LCM(70,243) = 17010
