So the greatest common factor 66,77,728 is 1.
Lets's calculate LCM of 558,409,807
3 | 558, 409, 807 |
186, 409, 269 |
∴ So the LCM of the given numbers is 3 x 186 x 409 x 269 = 61391718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/61391718
Therefore, the GCF of Fractions 66/558,77/409,728/807 is 1/61391718
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 558,409,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(558,409,807) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(558,409,807) x common factors =1 x 3 = 3
LCM(558,409,807) = ( 558 × 409 × 807 ) / 3
LCM(558,409,807) = 184175154 / 3
LCM(558,409,807) = 61391718
