Greatest Common Factor
We found the factors 308,940 . The biggest common factor number is the GCF number.
So the greatest common factor 308,940 is 4.
Lets's calculate LCM of 35,642
Given numbers has no common factors except 1. So, there LCM is their product i.e 22470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/22470
Therefore, the GCF of Fractions 308/35,940/642 is 4/22470
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 35,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,642) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(35,642) x common factors =1 x 1 = 1
LCM(35,642) = ( 35 × 642 ) / 1
LCM(35,642) = 22470 / 1
LCM(35,642) = 22470
