Lets's calculate LCM of 425,269,547
Given numbers has no common factors except 1. So, there LCM is their product i.e 62535775
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/62535775
Therefore, the GCF of Fractions 38/425,75/269,399/547 is 1/62535775
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 425,269,547 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(425,269,547) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(425,269,547) x common factors =1 x 1 = 1
LCM(425,269,547) = ( 425 × 269 × 547 ) / 1
LCM(425,269,547) = 62535775 / 1
LCM(425,269,547) = 62535775
