Lets's calculate LCM of 149,545
Given numbers has no common factors except 1. So, there LCM is their product i.e 81205
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/81205
Therefore, the GCF of Fractions 640/149,7117/545 is 1/81205
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 149,545 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(149,545) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(149,545) x common factors =1 x 1 = 1
LCM(149,545) = ( 149 × 545 ) / 1
LCM(149,545) = 81205 / 1
LCM(149,545) = 81205
