So the greatest common factor 442,646 is 34.
Lets's calculate LCM of 122,792
2 | 122, 792 |
61, 396 |
∴ So the LCM of the given numbers is 2 x 61 x 396 = 48312
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 34/48312
Therefore, the GCF of Fractions 442/122,646/792 is 34/48312
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 122,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(122,792) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(122,792) x common factors =2 x 1 = 2
LCM(122,792) = ( 122 × 792 ) / 2
LCM(122,792) = 96624 / 2
LCM(122,792) = 48312
