Greatest Common Factor
We found the factors 700,7748 . The biggest common factor number is the GCF number.
So the greatest common factor 700,7748 is 4.
Lets's calculate LCM of 407,178
Given numbers has no common factors except 1. So, there LCM is their product i.e 72446
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/72446
Therefore, the GCF of Fractions 700/407,7748/178 is 4/72446
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 407,178 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(407,178) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(407,178) x common factors =1 x 1 = 1
LCM(407,178) = ( 407 × 178 ) / 1
LCM(407,178) = 72446 / 1
LCM(407,178) = 72446
