Given Input Data is 165, 781, 351
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 165 is 3 x 5 x 11
Prime Factorization of 781 is 11 x 71
Prime Factorization of 351 is 3 x 3 x 3 x 13

Finding GCD of 165, 781, 351 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(165, 781) = 11715
GCD(165, 781) = ( 165 x 781 ) / 11715
GCD(165, 781) = 128865 / 11715
GCD(165, 781) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 351
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 351) = 3861
GCD(11, 351) = ( 11 x 351 ) / 3861
GCD(11, 351) = 3861 / 3861
GCD(11, 351) = 1
GCD of 165, 781, 351 is 1
