Lets's calculate LCM of 156,838
2 | 156, 838 |
78, 419 |
∴ So the LCM of the given numbers is 2 x 78 x 419 = 65364
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65364
Therefore, the GCF of Fractions 680/156,293/838 is 1/65364
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 156,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(156,838) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(156,838) x common factors =2 x 1 = 2
LCM(156,838) = ( 156 × 838 ) / 2
LCM(156,838) = 130728 / 2
LCM(156,838) = 65364
