Lets's calculate LCM of 660,789
3 | 660, 789 |
220, 263 |
∴ So the LCM of the given numbers is 3 x 220 x 263 = 173580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/173580
Therefore, the GCF of Fractions 772/660,8216/789 is 4/173580
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 660,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(660,789) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(660,789) x common factors =3 x 1 = 3
LCM(660,789) = ( 660 × 789 ) / 3
LCM(660,789) = 520740 / 3
LCM(660,789) = 173580
