Greatest Common Factor
We found the factors 640,647 . The biggest common factor number is the GCF number.
So the greatest common factor 640,647 is 1.
Lets's calculate LCM of 92,2278
2 | 92, 2278 |
46, 1139 |
∴ So the LCM of the given numbers is 2 x 46 x 1139 = 104788
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/104788
Therefore, the GCF of Fractions 640/92,647/2278 is 1/104788
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 92,2278 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,2278) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(92,2278) x common factors =2 x 1 = 2
LCM(92,2278) = ( 92 × 2278 ) / 2
LCM(92,2278) = 209576 / 2
LCM(92,2278) = 104788
