Now, list down the factors of 7254
:1,2,3,6,9,13,18,26,31,39,62,78,93,117,186,234,279,403,558,806,1209,2418,3627,7254
Greatest Common Factor
We found the factors 1997,7254 . The biggest common factor number is the GCF number.
So the greatest common factor 1997,7254 is 1.
Lets's calculate LCM of 645,4157
Given numbers has no common factors except 1. So, there LCM is their product i.e 2681265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2681265
Therefore, the GCF of Fractions 1997/645,7254/4157 is 1/2681265
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 645,4157 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,4157) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,4157) x common factors =1 x 1 = 1
LCM(645,4157) = ( 645 × 4157 ) / 1
LCM(645,4157) = 2681265 / 1
LCM(645,4157) = 2681265
