The HCF of 89,39,40 is 1.
Lets's calculate GCF of 89,39,40
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 89
:1,89
Now, list down the factors of 39
:1,3,13,39
Now, list down the factors of 40
:1,2,4,5,8,10,20,40
Greatest Common Factor
We found the factors 89,39,40 . The biggest common factor number is the GCF number.
So the greatest common factor 89,39,40 is 1.
Lets's calculate LCM of 93,40,71
Given numbers has no common factors except 1. So, there LCM is their product i.e 264120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/264120
Therefore, the GCF of Fractions 89/93,39/40,40/71 is 1/264120
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 93,40,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(93,40,71) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(93,40,71) x common factors =1 x 1 = 1
LCM(93,40,71) = ( 93 × 40 × 71 ) / 1
LCM(93,40,71) = 264120 / 1
LCM(93,40,71) = 264120
