:1,2,349,698
Greatest Common Factor
We found the factors 680,698 . The biggest common factor number is the GCF number.
So the greatest common factor 680,698 is 2.
Lets's calculate LCM of 61,477
Given numbers has no common factors except 1. So, there LCM is their product i.e 29097
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/29097
Therefore, the GCF of Fractions 680/61,698/477 is 2/29097
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 61,477 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,477) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,477) x common factors =1 x 1 = 1
LCM(61,477) = ( 61 × 477 ) / 1
LCM(61,477) = 29097 / 1
LCM(61,477) = 29097
