Lets's calculate GCF of 20,4154
2 | 20, 4154 |
10, 2077 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 20
:1,2,4,5,10,20
Now, list down the factors of 4154
:1,2,31,62,67,134,2077,4154
Greatest Common Factor
We found the factors 20,4154 . The biggest common factor number is the GCF number.
So the greatest common factor 20,4154 is 2.
Lets's calculate LCM of 128,2011
Given numbers has no common factors except 1. So, there LCM is their product i.e 257408
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/257408
Therefore, the GCF of Fractions 20/128,4154/2011 is 2/257408
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 128,2011 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,2011) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(128,2011) x common factors =1 x 1 = 1
LCM(128,2011) = ( 128 × 2011 ) / 1
LCM(128,2011) = 257408 / 1
LCM(128,2011) = 257408
