Lets's calculate LCM of 656,168
2 | 656, 168 |
2 | 328, 84 |
2 | 164, 42 |
82, 21 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 82 x 21 = 13776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13776
Therefore, the GCF of Fractions 1967/656,8780/168 is 1/13776
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 656,168 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(656,168) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(656,168) x common factors =8 x 1 = 8
LCM(656,168) = ( 656 × 168 ) / 8
LCM(656,168) = 110208 / 8
LCM(656,168) = 13776
