Greatest Common Factor
We found the factors 66,221,774 . The biggest common factor number is the GCF number.
So the greatest common factor 66,221,774 is 1.
Lets's calculate LCM of 58,55,831
Given numbers has no common factors except 1. So, there LCM is their product i.e 2650890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2650890
Therefore, the GCF of Fractions 66/58,221/55,774/831 is 1/2650890
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 58,55,831 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,55,831) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(58,55,831) x common factors =1 x 1 = 1
LCM(58,55,831) = ( 58 × 55 × 831 ) / 1
LCM(58,55,831) = 2650890 / 1
LCM(58,55,831) = 2650890
