The HCF of 255,154 is 1.
Lets's calculate GCF of 255,154
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 255
:1,3,5,15,17,51,85,255
Now, list down the factors of 154
:1,2,7,11,14,22,77,154
Greatest Common Factor
We found the factors 255,154 . The biggest common factor number is the GCF number.
So the greatest common factor 255,154 is 1.
Lets's calculate LCM of 167,870
Given numbers has no common factors except 1. So, there LCM is their product i.e 145290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/145290
Therefore, the GCF of Fractions 255/167,154/870 is 1/145290
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 167,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(167,870) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(167,870) x common factors =1 x 1 = 1
LCM(167,870) = ( 167 × 870 ) / 1
LCM(167,870) = 145290 / 1
LCM(167,870) = 145290
