Lets's calculate LCM of 320,792
2 | 320, 792 |
2 | 160, 396 |
2 | 80, 198 |
40, 99 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 40 x 99 = 31680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31680
Therefore, the GCF of Fractions 658/320,165/792 is 1/31680
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 320,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(320,792) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(320,792) x common factors =8 x 1 = 8
LCM(320,792) = ( 320 × 792 ) / 8
LCM(320,792) = 253440 / 8
LCM(320,792) = 31680
