Greatest Common Factor
We found the factors 172,669 . The biggest common factor number is the GCF number.
So the greatest common factor 172,669 is 1.
Lets's calculate LCM of 372,749
Given numbers has no common factors except 1. So, there LCM is their product i.e 278628
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/278628
Therefore, the GCF of Fractions 172/372,669/749 is 1/278628
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 372,749 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(372,749) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(372,749) x common factors =1 x 1 = 1
LCM(372,749) = ( 372 × 749 ) / 1
LCM(372,749) = 278628 / 1
LCM(372,749) = 278628
