Factors of 134
List of positive integer factors of 134 that divides 134 without a remainder.
1,2,67,134
Greatest Common Factor
We found the factors 168,134 . The biggest common factor number is the GCF number.
So the greatest common factor 168,134 is 2.
Lets's calculate LCM of 5680,2991
Given numbers has no common factors except 1. So, there LCM is their product i.e 16988880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16988880
Therefore, the GCF of Fractions 168/5680,134/2991 is 2/16988880
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 5680,2991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(5680,2991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(5680,2991) x common factors =1 x 1 = 1
LCM(5680,2991) = ( 5680 × 2991 ) / 1
LCM(5680,2991) = 16988880 / 1
LCM(5680,2991) = 16988880
