:1,3,13,19,39,57,247,741
Greatest Common Factor
We found the factors 156,741 . The biggest common factor number is the GCF number.
So the greatest common factor 156,741 is 39.
Lets's calculate LCM of 945,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 743715
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/743715
Therefore, the GCF of Fractions 156/945,741/787 is 39/743715
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 945,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(945,787) x common factors =1 x 1 = 1
LCM(945,787) = ( 945 × 787 ) / 1
LCM(945,787) = 743715 / 1
LCM(945,787) = 743715
