Greatest Common Factor
We found the factors 1485,2898 . The biggest common factor number is the GCF number.
So the greatest common factor 1485,2898 is 9.
Lets's calculate LCM of 691,1239
Given numbers has no common factors except 1. So, there LCM is their product i.e 856149
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/856149
Therefore, the GCF of Fractions 1485/691,2898/1239 is 9/856149
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 691,1239 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,1239) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(691,1239) x common factors =1 x 1 = 1
LCM(691,1239) = ( 691 × 1239 ) / 1
LCM(691,1239) = 856149 / 1
LCM(691,1239) = 856149
