So the greatest common factor 636,644 is 4.
Lets's calculate LCM of 65,2915
5 | 65, 2915 |
13, 583 |
∴ So the LCM of the given numbers is 5 x 13 x 583 = 37895
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/37895
Therefore, the GCF of Fractions 636/65,644/2915 is 4/37895
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 65,2915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,2915) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,2915) x common factors =5 x 1 = 5
LCM(65,2915) = ( 65 × 2915 ) / 5
LCM(65,2915) = 189475 / 5
LCM(65,2915) = 37895
