Lets's calculate GCF of 18,461,895
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 18
:1,2,3,6,9,18
Now, list down the factors of 461
:1,461
Now, list down the factors of 895
:1,5,179,895
Greatest Common Factor
We found the factors 18,461,895 . The biggest common factor number is the GCF number.
So the greatest common factor 18,461,895 is 1.
Lets's calculate LCM of 20,51,211
Given numbers has no common factors except 1. So, there LCM is their product i.e 215220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/215220
Therefore, the GCF of Fractions 18/20,461/51,895/211 is 1/215220
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 20,51,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,51,211) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(20,51,211) x common factors =1 x 1 = 1
LCM(20,51,211) = ( 20 × 51 × 211 ) / 1
LCM(20,51,211) = 215220 / 1
LCM(20,51,211) = 215220
