So the greatest common factor 1689,1236 is 3.
Lets's calculate LCM of 364,362
2 | 364, 362 |
182, 181 |
∴ So the LCM of the given numbers is 2 x 182 x 181 = 65884
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/65884
Therefore, the GCF of Fractions 1689/364,1236/362 is 3/65884
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 364,362 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(364,362) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(364,362) x common factors =2 x 1 = 2
LCM(364,362) = ( 364 × 362 ) / 2
LCM(364,362) = 131768 / 2
LCM(364,362) = 65884
