Greatest Common Factor
We found the factors 171,9747 . The biggest common factor number is the GCF number.
So the greatest common factor 171,9747 is 171.
Lets's calculate LCM of 742,863
Given numbers has no common factors except 1. So, there LCM is their product i.e 640346
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 171/640346
Therefore, the GCF of Fractions 171/742,9747/863 is 171/640346
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 742,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(742,863) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(742,863) x common factors =1 x 1 = 1
LCM(742,863) = ( 742 × 863 ) / 1
LCM(742,863) = 640346 / 1
LCM(742,863) = 640346
