Lets's calculate LCM of 748,755
Given numbers has no common factors except 1. So, there LCM is their product i.e 564740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/564740
Therefore, the GCF of Fractions 868/748,389/755 is 1/564740
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 748,755 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(748,755) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(748,755) x common factors =1 x 1 = 1
LCM(748,755) = ( 748 × 755 ) / 1
LCM(748,755) = 564740 / 1
LCM(748,755) = 564740
