Now, list down the factors of 121
:1,11,121
Greatest Common Factor
We found the factors 172,121 . The biggest common factor number is the GCF number.
So the greatest common factor 172,121 is 1.
Lets's calculate LCM of 770,236
2 | 770, 236 |
385, 118 |
∴ So the LCM of the given numbers is 2 x 385 x 118 = 90860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/90860
Therefore, the GCF of Fractions 172/770,121/236 is 1/90860
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 770,236 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(770,236) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(770,236) x common factors =2 x 1 = 2
LCM(770,236) = ( 770 × 236 ) / 2
LCM(770,236) = 181720 / 2
LCM(770,236) = 90860
