1,2,4,8,16,32,64,128
Greatest Common Factor
We found the factors 80,609,128 . The biggest common factor number is the GCF number.
So the greatest common factor 80,609,128 is 1.
Lets's calculate LCM of 21,86,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 554442
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/554442
Therefore, the GCF of Fractions 80/21,609/86,128/307 is 1/554442
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 21,86,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,86,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,86,307) x common factors =1 x 1 = 1
LCM(21,86,307) = ( 21 × 86 × 307 ) / 1
LCM(21,86,307) = 554442 / 1
LCM(21,86,307) = 554442
Here are some samples of GCF of Fractions calculations.
