Greatest Common Factor
We found the factors 27,42,897 . The biggest common factor number is the GCF number.
So the greatest common factor 27,42,897 is 3.
Lets's calculate LCM of 91,869,120
Given numbers has no common factors except 1. So, there LCM is their product i.e 9489480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/9489480
Therefore, the GCF of Fractions 27/91,42/869,897/120 is 3/9489480
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 91,869,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,869,120) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,869,120) x common factors =1 x 1 = 1
LCM(91,869,120) = ( 91 × 869 × 120 ) / 1
LCM(91,869,120) = 9489480 / 1
LCM(91,869,120) = 9489480
