Lets's calculate GCF of 785,170
5 | 785, 170 |
157, 34 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 785
:1,5,157,785
Now, list down the factors of 170
:1,2,5,10,17,34,85,170
Greatest Common Factor
We found the factors 785,170 . The biggest common factor number is the GCF number.
So the greatest common factor 785,170 is 5.
Lets's calculate LCM of 245,543
Given numbers has no common factors except 1. So, there LCM is their product i.e 133035
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/133035
Therefore, the GCF of Fractions 785/245,170/543 is 5/133035
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 245,543 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(245,543) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(245,543) x common factors =1 x 1 = 1
LCM(245,543) = ( 245 × 543 ) / 1
LCM(245,543) = 133035 / 1
LCM(245,543) = 133035
