Greatest Common Factor
We found the factors 98,12,206 . The biggest common factor number is the GCF number.
So the greatest common factor 98,12,206 is 2.
Lets's calculate LCM of 47,18,143
Given numbers has no common factors except 1. So, there LCM is their product i.e 120978
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/120978
Therefore, the GCF of Fractions 98/47,12/18,206/143 is 2/120978
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 47,18,143 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,18,143) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,18,143) x common factors =1 x 1 = 1
LCM(47,18,143) = ( 47 × 18 × 143 ) / 1
LCM(47,18,143) = 120978 / 1
LCM(47,18,143) = 120978
