Greatest Common Factor
We found the factors 1420,2840 . The biggest common factor number is the GCF number.
So the greatest common factor 1420,2840 is 1420.
Lets's calculate LCM of 731,820
Given numbers has no common factors except 1. So, there LCM is their product i.e 599420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1420/599420
Therefore, the GCF of Fractions 1420/731,2840/820 is 1420/599420
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 731,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(731,820) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(731,820) x common factors =1 x 1 = 1
LCM(731,820) = ( 731 × 820 ) / 1
LCM(731,820) = 599420 / 1
LCM(731,820) = 599420
