We found the factors 202,420 . The biggest common factor number is the GCF number.
So the greatest common factor 202,420 is 2.
Lets's calculate LCM of 74,874
2 | 74, 874 |
37, 437 |
∴ So the LCM of the given numbers is 2 x 37 x 437 = 32338
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/32338
Therefore, the GCF of Fractions 202/74,420/874 is 2/32338
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 74,874 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,874) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(74,874) x common factors =2 x 1 = 2
LCM(74,874) = ( 74 × 874 ) / 2
LCM(74,874) = 64676 / 2
LCM(74,874) = 32338
