Greatest Common Factor
We found the factors 7,87,61,942 . The biggest common factor number is the GCF number.
So the greatest common factor 7,87,61,942 is 1.
Lets's calculate LCM of 53,88,212,247
2 | 53, 88, 212, 247 |
2 | 53, 44, 106, 247 |
53 | 53, 22, 53, 247 |
1, 22, 1, 247 |
∴ So the LCM of the given numbers is 2 x 2 x 53 x 1 x 22 x 1 x 247 = 1152008
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1152008
Therefore, the GCF of Fractions 7/53,87/88,61/212,942/247 is 1/1152008
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 53,88,212,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(53,88,212,247) = 1
common factors(in case of two or more numbers have common factors) = 212
GCF(53,88,212,247) x common factors =1 x 212 = 212
LCM(53,88,212,247) = ( 53 × 88 × 212 × 247 ) / 212
LCM(53,88,212,247) = 244225696 / 212
LCM(53,88,212,247) = 1152008
