Lets's calculate LCM of 654,768
2 | 654, 768 |
3 | 327, 384 |
109, 128 |
∴ So the LCM of the given numbers is 2 x 3 x 109 x 128 = 83712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83712
Therefore, the GCF of Fractions 7769/654,8912/768 is 1/83712
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 654,768 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(654,768) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(654,768) x common factors =6 x 1 = 6
LCM(654,768) = ( 654 × 768 ) / 6
LCM(654,768) = 502272 / 6
LCM(654,768) = 83712
