Lets's calculate LCM of 65,27,372
3 | 65, 27, 372 |
65, 9, 124 |
∴ So the LCM of the given numbers is 3 x 65 x 9 x 124 = 217620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/217620
Therefore, the GCF of Fractions 61/65,990/27,590/372 is 1/217620
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 65,27,372 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,27,372) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(65,27,372) x common factors =1 x 3 = 3
LCM(65,27,372) = ( 65 × 27 × 372 ) / 3
LCM(65,27,372) = 652860 / 3
LCM(65,27,372) = 217620
