Greatest Common Factor
We found the factors 845,489 . The biggest common factor number is the GCF number.
So the greatest common factor 845,489 is 1.
Lets's calculate LCM of 974,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 117854
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/117854
Therefore, the GCF of Fractions 845/974,489/121 is 1/117854
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 974,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(974,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(974,121) x common factors =1 x 1 = 1
LCM(974,121) = ( 974 × 121 ) / 1
LCM(974,121) = 117854 / 1
LCM(974,121) = 117854
