Greatest Common Factor
We found the factors 771,221 . The biggest common factor number is the GCF number.
So the greatest common factor 771,221 is 1.
Lets's calculate LCM of 961,961
31 | 961, 961 |
31 | 31, 31 |
1, 1 |
∴ So the LCM of the given numbers is 31 x 31 x 1 x 1 = 961
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/961
Therefore, the GCF of Fractions 771/961,221/961 is 1/961
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 961,961 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(961,961) = 961
common factors(in case of two or more numbers have common factors) = 1
GCF(961,961) x common factors =961 x 1 = 961
LCM(961,961) = ( 961 × 961 ) / 961
LCM(961,961) = 923521 / 961
LCM(961,961) = 961
