:1,2,7,14,23,46,161,322
Now, list down the factors of 280
:1,2,4,5,7,8,10,14,20,28,35,40,56,70,140,280
Greatest Common Factor
We found the factors 66,322,280 . The biggest common factor number is the GCF number.
So the greatest common factor 66,322,280 is 2.
Lets's calculate LCM of 19,43,663
Given numbers has no common factors except 1. So, there LCM is their product i.e 541671
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/541671
Therefore, the GCF of Fractions 66/19,322/43,280/663 is 2/541671
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 19,43,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,43,663) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,43,663) x common factors =1 x 1 = 1
LCM(19,43,663) = ( 19 × 43 × 663 ) / 1
LCM(19,43,663) = 541671 / 1
LCM(19,43,663) = 541671
