1,7,23,31,161,217,713,4991
Greatest Common Factor
We found the factors 485,4991 . The biggest common factor number is the GCF number.
So the greatest common factor 485,4991 is 1.
Lets's calculate LCM of 762,1778
2 | 762, 1778 |
127 | 381, 889 |
3, 7 |
∴ So the LCM of the given numbers is 2 x 127 x 3 x 7 = 5334
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5334
Therefore, the GCF of Fractions 485/762,4991/1778 is 1/5334
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 762,1778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(762,1778) = 254
common factors(in case of two or more numbers have common factors) = 1
GCF(762,1778) x common factors =254 x 1 = 254
LCM(762,1778) = ( 762 × 1778 ) / 254
LCM(762,1778) = 1354836 / 254
LCM(762,1778) = 5334
