:1,3,9,109,327,981
Now, list down the factors of 275
:1,5,11,25,55,275
Greatest Common Factor
We found the factors 981,275 . The biggest common factor number is the GCF number.
So the greatest common factor 981,275 is 1.
Lets's calculate LCM of 643,984
Given numbers has no common factors except 1. So, there LCM is their product i.e 632712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/632712
Therefore, the GCF of Fractions 981/643,275/984 is 1/632712
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 643,984 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,984) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,984) x common factors =1 x 1 = 1
LCM(643,984) = ( 643 × 984 ) / 1
LCM(643,984) = 632712 / 1
LCM(643,984) = 632712
