We found the factors 760,800 . The biggest common factor number is the GCF number.
So the greatest common factor 760,800 is 40.
Lets's calculate LCM of 1266,4982
2 | 1266, 4982 |
633, 2491 |
∴ So the LCM of the given numbers is 2 x 633 x 2491 = 3153606
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/3153606
Therefore, the GCF of Fractions 760/1266,800/4982 is 40/3153606
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 1266,4982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1266,4982) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(1266,4982) x common factors =2 x 1 = 2
LCM(1266,4982) = ( 1266 × 4982 ) / 2
LCM(1266,4982) = 6307212 / 2
LCM(1266,4982) = 3153606
