Greatest Common Factor
We found the factors 274,835,840 . The biggest common factor number is the GCF number.
So the greatest common factor 274,835,840 is 1.
Lets's calculate LCM of 711,397,421
Given numbers has no common factors except 1. So, there LCM is their product i.e 118834407
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/118834407
Therefore, the GCF of Fractions 274/711,835/397,840/421 is 1/118834407
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 711,397,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(711,397,421) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(711,397,421) x common factors =1 x 1 = 1
LCM(711,397,421) = ( 711 × 397 × 421 ) / 1
LCM(711,397,421) = 118834407 / 1
LCM(711,397,421) = 118834407
