To find the highest common factor of 812,857, we have to find the factors of both numbers and list the highest common factor.
The factors of 812 are 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
The factors of 857 are 1, 857
The HCF of 812,857 is 1.
Lets's calculate GCF of 812,857
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 812
:1,2,4,7,14,28,29,58,116,203,406,812
Now, list down the factors of 857
:1,857
Greatest Common Factor
We found the factors 812,857 . The biggest common factor number is the GCF number.
So the greatest common factor 812,857 is 1.
Lets's calculate LCM of 124,159
Given numbers has no common factors except 1. So, there LCM is their product i.e 19716
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19716
Therefore, the GCF of Fractions 812/124,857/159 is 1/19716
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 124,159 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(124,159) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(124,159) x common factors =1 x 1 = 1
LCM(124,159) = ( 124 × 159 ) / 1
LCM(124,159) = 19716 / 1
LCM(124,159) = 19716
