Given numbers are 161, 921, 565, 923

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

Apply this formula for all numbers.

Step1:

LCM(161, 921) = 148281

GCD(161, 921) = ( 161 x 921 ) / 148281

= 161 / 921

= 161

Step2:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

Step3:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

So, Greatest Common Divisor of 161, 921, 565, 923 is 1
