Lets's calculate LCM of 63,7247
Given numbers has no common factors except 1. So, there LCM is their product i.e 456561
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/456561
Therefore, the GCF of Fractions 495/63,945/7247 is 45/456561
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 63,7247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,7247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(63,7247) x common factors =1 x 1 = 1
LCM(63,7247) = ( 63 × 7247 ) / 1
LCM(63,7247) = 456561 / 1
LCM(63,7247) = 456561
