Given numbers are 921, 551, 327, 165

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

Apply this formula for all numbers.

Step1:

LCM(921, 551) = 507471

GCD(921, 551) = ( 921 x 551 ) / 507471

= 921 / 551

= 921

Step2:

LCM(1, 327) = 327

GCD(1, 327) = ( 1 x 327 ) / 327

= 1 / 327

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 921, 551, 327, 165 is 1
