The factors of 331 are 1, 331
The HCF of 620,331 is 1.
Lets's calculate GCF of 620,331
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 620
:1,2,4,5,10,20,31,62,124,155,310,620
Now, list down the factors of 331
:1,331
Greatest Common Factor
We found the factors 620,331 . The biggest common factor number is the GCF number.
So the greatest common factor 620,331 is 1.
Lets's calculate LCM of 697,361
Given numbers has no common factors except 1. So, there LCM is their product i.e 251617
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/251617
Therefore, the GCF of Fractions 620/697,331/361 is 1/251617
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 697,361 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(697,361) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(697,361) x common factors =1 x 1 = 1
LCM(697,361) = ( 697 × 361 ) / 1
LCM(697,361) = 251617 / 1
LCM(697,361) = 251617
