Greatest Common Factor
We found the factors 972,948 . The biggest common factor number is the GCF number.
So the greatest common factor 972,948 is 12.
Lets's calculate LCM of 421,412
Given numbers has no common factors except 1. So, there LCM is their product i.e 173452
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/173452
Therefore, the GCF of Fractions 972/421,948/412 is 12/173452
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 421,412 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,412) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,412) x common factors =1 x 1 = 1
LCM(421,412) = ( 421 × 412 ) / 1
LCM(421,412) = 173452 / 1
LCM(421,412) = 173452
