Given numbers are 361, 165, 438

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(361, 165) = 59565

GCD(361, 165) = ( 361 x 165 ) / 59565

= 361 / 165

= 361

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 361, 165, 438 is 1
