The factors of 391 are 1, 17, 23, 391
The HCF of 580,391 is 1.
Lets's calculate GCF of 580,391
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 580
:1,2,4,5,10,20,29,58,116,145,290,580
Now, list down the factors of 391
:1,17,23,391
Greatest Common Factor
We found the factors 580,391 . The biggest common factor number is the GCF number.
So the greatest common factor 580,391 is 1.
Lets's calculate LCM of 51,980
Given numbers has no common factors except 1. So, there LCM is their product i.e 49980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/49980
Therefore, the GCF of Fractions 580/51,391/980 is 1/49980
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 51,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,980) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(51,980) x common factors =1 x 1 = 1
LCM(51,980) = ( 51 × 980 ) / 1
LCM(51,980) = 49980 / 1
LCM(51,980) = 49980
