The factors of 985 are 1, 5, 197, 985
The HCF of 197,985 is 197.
Lets's calculate GCF of 197,985
197 | 197, 985 |
1, 5 |
∴ So the GCF of the given numbers is 197 = 197
Now, list down the factors of 197
:1,197
Now, list down the factors of 985
:1,5,197,985
Greatest Common Factor
We found the factors 197,985 . The biggest common factor number is the GCF number.
So the greatest common factor 197,985 is 197.
Lets's calculate LCM of 217,254
Given numbers has no common factors except 1. So, there LCM is their product i.e 55118
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 197/55118
Therefore, the GCF of Fractions 197/217,985/254 is 197/55118
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 217,254 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(217,254) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(217,254) x common factors =1 x 1 = 1
LCM(217,254) = ( 217 × 254 ) / 1
LCM(217,254) = 55118 / 1
LCM(217,254) = 55118
