Greatest Common Factor
We found the factors 608,342 . The biggest common factor number is the GCF number.
So the greatest common factor 608,342 is 38.
Lets's calculate LCM of 398,709
Given numbers has no common factors except 1. So, there LCM is their product i.e 282182
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 38/282182
Therefore, the GCF of Fractions 608/398,342/709 is 38/282182
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 398,709 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,709) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(398,709) x common factors =1 x 1 = 1
LCM(398,709) = ( 398 × 709 ) / 1
LCM(398,709) = 282182 / 1
LCM(398,709) = 282182
