:1,457
Now, list down the factors of 272
:1,2,4,8,16,17,34,68,136,272
Greatest Common Factor
We found the factors 457,272 . The biggest common factor number is the GCF number.
So the greatest common factor 457,272 is 1.
Lets's calculate LCM of 79,421
Given numbers has no common factors except 1. So, there LCM is their product i.e 33259
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33259
Therefore, the GCF of Fractions 457/79,272/421 is 1/33259
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 79,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,421) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,421) x common factors =1 x 1 = 1
LCM(79,421) = ( 79 × 421 ) / 1
LCM(79,421) = 33259 / 1
LCM(79,421) = 33259
