The factors of 20 are 1, 2, 4, 5, 10, 20
The factors of 17 are 1, 17
The HCF of 20,17 is 1.
Lets's calculate GCF of 20,17
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 20
:1,2,4,5,10,20
Now, list down the factors of 17
:1,17
Greatest Common Factor
We found the factors 20,17 . The biggest common factor number is the GCF number.
So the greatest common factor 20,17 is 1.
Lets's calculate LCM of 971,3716
Given numbers has no common factors except 1. So, there LCM is their product i.e 3608236
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3608236
Therefore, the GCF of Fractions 20/971,17/3716 is 1/3608236
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 971,3716 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(971,3716) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(971,3716) x common factors =1 x 1 = 1
LCM(971,3716) = ( 971 × 3716 ) / 1
LCM(971,3716) = 3608236 / 1
LCM(971,3716) = 3608236
