1,2,4,23,46,92
Greatest Common Factor
We found the factors 75,51,61,92 . The biggest common factor number is the GCF number.
So the greatest common factor 75,51,61,92 is 1.
Lets's calculate LCM of 94,63,55,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 256333770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/256333770
Therefore, the GCF of Fractions 75/94,51/63,61/55,92/787 is 1/256333770
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 94,63,55,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,63,55,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(94,63,55,787) x common factors =1 x 1 = 1
LCM(94,63,55,787) = ( 94 × 63 × 55 × 787 ) / 1
LCM(94,63,55,787) = 256333770 / 1
LCM(94,63,55,787) = 256333770
Here are some samples of GCF of Fractions calculations.
