Lets's calculate GCF of 921,938
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 921
:1,3,307,921
Now, list down the factors of 938
:1,2,7,14,67,134,469,938
Greatest Common Factor
We found the factors 921,938 . The biggest common factor number is the GCF number.
So the greatest common factor 921,938 is 1.
Lets's calculate LCM of 901,981
Given numbers has no common factors except 1. So, there LCM is their product i.e 883881
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/883881
Therefore, the GCF of Fractions 921/901,938/981 is 1/883881
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 901,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(901,981) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(901,981) x common factors =1 x 1 = 1
LCM(901,981) = ( 901 × 981 ) / 1
LCM(901,981) = 883881 / 1
LCM(901,981) = 883881
