Lets's calculate LCM of 768,2882
2 | 768, 2882 |
384, 1441 |
∴ So the LCM of the given numbers is 2 x 384 x 1441 = 1106688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/1106688
Therefore, the GCF of Fractions 28/768,6636/2882 is 28/1106688
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 768,2882 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,2882) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(768,2882) x common factors =2 x 1 = 2
LCM(768,2882) = ( 768 × 2882 ) / 2
LCM(768,2882) = 2213376 / 2
LCM(768,2882) = 1106688
