So the greatest common factor 665,752 is 1.
Lets's calculate LCM of 456,478
2 | 456, 478 |
228, 239 |
∴ So the LCM of the given numbers is 2 x 228 x 239 = 108984
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/108984
Therefore, the GCF of Fractions 665/456,752/478 is 1/108984
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 456,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(456,478) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(456,478) x common factors =2 x 1 = 2
LCM(456,478) = ( 456 × 478 ) / 2
LCM(456,478) = 217968 / 2
LCM(456,478) = 108984
