Lets's calculate GCF of 280,202
2 | 280, 202 |
140, 101 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 280
:1,2,4,5,7,8,10,14,20,28,35,40,56,70,140,280
Now, list down the factors of 202
:1,2,101,202
Greatest Common Factor
We found the factors 280,202 . The biggest common factor number is the GCF number.
So the greatest common factor 280,202 is 2.
Lets's calculate LCM of 311,197
Given numbers has no common factors except 1. So, there LCM is their product i.e 61267
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/61267
Therefore, the GCF of Fractions 280/311,202/197 is 2/61267
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 311,197 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,197) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(311,197) x common factors =1 x 1 = 1
LCM(311,197) = ( 311 × 197 ) / 1
LCM(311,197) = 61267 / 1
LCM(311,197) = 61267
