Factors of 7142
List of positive integer factors of 7142 that divides 7142 without a remainder.
1,2,3571,7142
Greatest Common Factor
We found the factors 656,7142 . The biggest common factor number is the GCF number.
So the greatest common factor 656,7142 is 2.
Lets's calculate LCM of 470,539
Given numbers has no common factors except 1. So, there LCM is their product i.e 253330
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/253330
Therefore, the GCF of Fractions 656/470,7142/539 is 2/253330
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 470,539 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,539) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(470,539) x common factors =1 x 1 = 1
LCM(470,539) = ( 470 × 539 ) / 1
LCM(470,539) = 253330 / 1
LCM(470,539) = 253330
