Greatest Common Factor
We found the factors 9,405,795 . The biggest common factor number is the GCF number.
So the greatest common factor 9,405,795 is 3.
Lets's calculate LCM of 79,49,90
Given numbers has no common factors except 1. So, there LCM is their product i.e 348390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/348390
Therefore, the GCF of Fractions 9/79,405/49,795/90 is 3/348390
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 79,49,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,49,90) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,49,90) x common factors =1 x 1 = 1
LCM(79,49,90) = ( 79 × 49 × 90 ) / 1
LCM(79,49,90) = 348390 / 1
LCM(79,49,90) = 348390
