Now, list down the factors of 281
:1,281
Now, list down the factors of 874
:1,2,19,23,38,46,437,874
Greatest Common Factor
We found the factors 281,874 . The biggest common factor number is the GCF number.
So the greatest common factor 281,874 is 1.
Lets's calculate LCM of 421,455
Given numbers has no common factors except 1. So, there LCM is their product i.e 191555
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/191555
Therefore, the GCF of Fractions 281/421,874/455 is 1/191555
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 421,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,455) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(421,455) x common factors =1 x 1 = 1
LCM(421,455) = ( 421 × 455 ) / 1
LCM(421,455) = 191555 / 1
LCM(421,455) = 191555
