:1,2,3,4,6,12,23,31,46,62,69,92,93,124,138,186,276,372,713,1426,2139,2852,4278,8556
Greatest Common Factor
We found the factors 1561,8556 . The biggest common factor number is the GCF number.
So the greatest common factor 1561,8556 is 1.
Lets's calculate LCM of 580,1687
Given numbers has no common factors except 1. So, there LCM is their product i.e 978460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/978460
Therefore, the GCF of Fractions 1561/580,8556/1687 is 1/978460
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 580,1687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(580,1687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(580,1687) x common factors =1 x 1 = 1
LCM(580,1687) = ( 580 × 1687 ) / 1
LCM(580,1687) = 978460 / 1
LCM(580,1687) = 978460
