:1,2,79,158
Now, list down the factors of 343
:1,7,49,343
Greatest Common Factor
We found the factors 158,343 . The biggest common factor number is the GCF number.
So the greatest common factor 158,343 is 1.
Lets's calculate LCM of 21,2246
Given numbers has no common factors except 1. So, there LCM is their product i.e 47166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47166
Therefore, the GCF of Fractions 158/21,343/2246 is 1/47166
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 21,2246 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,2246) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,2246) x common factors =1 x 1 = 1
LCM(21,2246) = ( 21 × 2246 ) / 1
LCM(21,2246) = 47166 / 1
LCM(21,2246) = 47166
