The factors of 231 are 1, 3, 7, 11, 21, 33, 77, 231
The factors of 826 are 1, 2, 7, 14, 59, 118, 413, 826
The HCF of 231,826 is 7.
Lets's calculate GCF of 231,826
7 | 231, 826 |
33, 118 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 231
:1,3,7,11,21,33,77,231
Now, list down the factors of 826
:1,2,7,14,59,118,413,826
Greatest Common Factor
We found the factors 231,826 . The biggest common factor number is the GCF number.
So the greatest common factor 231,826 is 7.
Lets's calculate LCM of 815,319
Given numbers has no common factors except 1. So, there LCM is their product i.e 259985
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/259985
Therefore, the GCF of Fractions 231/815,826/319 is 7/259985
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 815,319 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,319) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(815,319) x common factors =1 x 1 = 1
LCM(815,319) = ( 815 × 319 ) / 1
LCM(815,319) = 259985 / 1
LCM(815,319) = 259985
