Greatest Common Factor
We found the factors 745,249 . The biggest common factor number is the GCF number.
So the greatest common factor 745,249 is 1.
Lets's calculate LCM of 602,689
Given numbers has no common factors except 1. So, there LCM is their product i.e 414778
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/414778
Therefore, the GCF of Fractions 745/602,249/689 is 1/414778
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 602,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(602,689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(602,689) x common factors =1 x 1 = 1
LCM(602,689) = ( 602 × 689 ) / 1
LCM(602,689) = 414778 / 1
LCM(602,689) = 414778
