Lets's calculate GCF of 202,128
2 | 202, 128 |
101, 64 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 202
:1,2,101,202
Now, list down the factors of 128
:1,2,4,8,16,32,64,128
Greatest Common Factor
We found the factors 202,128 . The biggest common factor number is the GCF number.
So the greatest common factor 202,128 is 2.
Lets's calculate LCM of 497,801
Given numbers has no common factors except 1. So, there LCM is their product i.e 398097
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/398097
Therefore, the GCF of Fractions 202/497,128/801 is 2/398097
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 497,801 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,801) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(497,801) x common factors =1 x 1 = 1
LCM(497,801) = ( 497 × 801 ) / 1
LCM(497,801) = 398097 / 1
LCM(497,801) = 398097
