:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 272,420 . The biggest common factor number is the GCF number.
So the greatest common factor 272,420 is 4.
Lets's calculate LCM of 77,359
Given numbers has no common factors except 1. So, there LCM is their product i.e 27643
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/27643
Therefore, the GCF of Fractions 272/77,420/359 is 4/27643
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 77,359 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,359) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,359) x common factors =1 x 1 = 1
LCM(77,359) = ( 77 × 359 ) / 1
LCM(77,359) = 27643 / 1
LCM(77,359) = 27643
