Greatest Common Factor
We found the factors 57,67,18,93 . The biggest common factor number is the GCF number.
So the greatest common factor 57,67,18,93 is 1.
Lets's calculate LCM of 79,18,83,545
Given numbers has no common factors except 1. So, there LCM is their product i.e 64324170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/64324170
Therefore, the GCF of Fractions 57/79,67/18,18/83,93/545 is 1/64324170
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 79,18,83,545 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,18,83,545) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,18,83,545) x common factors =1 x 1 = 1
LCM(79,18,83,545) = ( 79 × 18 × 83 × 545 ) / 1
LCM(79,18,83,545) = 64324170 / 1
LCM(79,18,83,545) = 64324170
Here are some samples of GCF of Fractions calculations.
