Greatest Common Factor
We found the factors 705,842 . The biggest common factor number is the GCF number.
So the greatest common factor 705,842 is 1.
Lets's calculate LCM of 780,737
Given numbers has no common factors except 1. So, there LCM is their product i.e 574860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/574860
Therefore, the GCF of Fractions 705/780,842/737 is 1/574860
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 780,737 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,737) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(780,737) x common factors =1 x 1 = 1
LCM(780,737) = ( 780 × 737 ) / 1
LCM(780,737) = 574860 / 1
LCM(780,737) = 574860
