:1,2,3,5,6,10,15,30
Greatest Common Factor
We found the factors 2,80,30 . The biggest common factor number is the GCF number.
So the greatest common factor 2,80,30 is 2.
Lets's calculate LCM of 17,920,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 13778840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/13778840
Therefore, the GCF of Fractions 2/17,80/920,30/881 is 2/13778840
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 17,920,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,920,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,920,881) x common factors =1 x 1 = 1
LCM(17,920,881) = ( 17 × 920 × 881 ) / 1
LCM(17,920,881) = 13778840 / 1
LCM(17,920,881) = 13778840
