Greatest Common Factor
We found the factors 640,731,688 . The biggest common factor number is the GCF number.
So the greatest common factor 640,731,688 is 1.
Lets's calculate LCM of 75,28,127
Given numbers has no common factors except 1. So, there LCM is their product i.e 266700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/266700
Therefore, the GCF of Fractions 640/75,731/28,688/127 is 1/266700
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 75,28,127 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,28,127) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(75,28,127) x common factors =1 x 1 = 1
LCM(75,28,127) = ( 75 × 28 × 127 ) / 1
LCM(75,28,127) = 266700 / 1
LCM(75,28,127) = 266700
Here are some samples of GCF of Fractions calculations.
