Lets's calculate LCM of 768,790
2 | 768, 790 |
384, 395 |
∴ So the LCM of the given numbers is 2 x 384 x 395 = 303360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/303360
Therefore, the GCF of Fractions 875/768,1638/790 is 7/303360
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 768,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(768,790) x common factors =2 x 1 = 2
LCM(768,790) = ( 768 × 790 ) / 2
LCM(768,790) = 606720 / 2
LCM(768,790) = 303360
