:1,2,5,10,29,58,145,290
Greatest Common Factor
We found the factors 770,290 . The biggest common factor number is the GCF number.
So the greatest common factor 770,290 is 10.
Lets's calculate LCM of 66,231
3 | 66, 231 |
11 | 22, 77 |
2, 7 |
∴ So the LCM of the given numbers is 3 x 11 x 2 x 7 = 462
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/462
Therefore, the GCF of Fractions 770/66,290/231 is 10/462
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 66,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,231) = 33
common factors(in case of two or more numbers have common factors) = 1
GCF(66,231) x common factors =33 x 1 = 33
LCM(66,231) = ( 66 × 231 ) / 33
LCM(66,231) = 15246 / 33
LCM(66,231) = 462
