The HCF of 140,206 is 2.
Lets's calculate GCF of 140,206
2 | 140, 206 |
70, 103 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 140
:1,2,4,5,7,10,14,20,28,35,70,140
Now, list down the factors of 206
:1,2,103,206
Greatest Common Factor
We found the factors 140,206 . The biggest common factor number is the GCF number.
So the greatest common factor 140,206 is 2.
Lets's calculate LCM of 385,487
Given numbers has no common factors except 1. So, there LCM is their product i.e 187495
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/187495
Therefore, the GCF of Fractions 140/385,206/487 is 2/187495
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 385,487 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(385,487) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(385,487) x common factors =1 x 1 = 1
LCM(385,487) = ( 385 × 487 ) / 1
LCM(385,487) = 187495 / 1
LCM(385,487) = 187495
