:1,2,4,5,8,10,11,16,20,22,40,44,55,80,88,110,176,220,440,880
Greatest Common Factor
We found the factors 540,880 . The biggest common factor number is the GCF number.
So the greatest common factor 540,880 is 20.
Lets's calculate LCM of 561,830
Given numbers has no common factors except 1. So, there LCM is their product i.e 465630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/465630
Therefore, the GCF of Fractions 540/561,880/830 is 20/465630
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 561,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(561,830) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(561,830) x common factors =1 x 1 = 1
LCM(561,830) = ( 561 × 830 ) / 1
LCM(561,830) = 465630 / 1
LCM(561,830) = 465630
