:1,3,7,9,11,21,33,63,77,99,231,693
Now, list down the factors of 990
:1,2,3,5,6,9,10,11,15,18,22,30,33,45,55,66,90,99,110,165,198,330,495,990
Greatest Common Factor
We found the factors 11,693,990 . The biggest common factor number is the GCF number.
So the greatest common factor 11,693,990 is 11.
Lets's calculate LCM of 61,26,357
Given numbers has no common factors except 1. So, there LCM is their product i.e 566202
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/566202
Therefore, the GCF of Fractions 11/61,693/26,990/357 is 11/566202
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 61,26,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,26,357) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,26,357) x common factors =1 x 1 = 1
LCM(61,26,357) = ( 61 × 26 × 357 ) / 1
LCM(61,26,357) = 566202 / 1
LCM(61,26,357) = 566202
