Lets's calculate LCM of 672,766
2 | 672, 766 |
336, 383 |
∴ So the LCM of the given numbers is 2 x 336 x 383 = 257376
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 107/257376
Therefore, the GCF of Fractions 749/672,856/766 is 107/257376
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 672,766 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(672,766) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(672,766) x common factors =2 x 1 = 2
LCM(672,766) = ( 672 × 766 ) / 2
LCM(672,766) = 514752 / 2
LCM(672,766) = 257376
