Greatest Common Factor
We found the factors 71,940,221 . The biggest common factor number is the GCF number.
So the greatest common factor 71,940,221 is 1.
Lets's calculate LCM of 39,40,529
Given numbers has no common factors except 1. So, there LCM is their product i.e 825240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/825240
Therefore, the GCF of Fractions 71/39,940/40,221/529 is 1/825240
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 39,40,529 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,40,529) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,40,529) x common factors =1 x 1 = 1
LCM(39,40,529) = ( 39 × 40 × 529 ) / 1
LCM(39,40,529) = 825240 / 1
LCM(39,40,529) = 825240
