Given numbers are 236, 561, 231, 921

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

Apply this formula for all numbers.

Step1:

LCM(236, 561) = 132396

GCD(236, 561) = ( 236 x 561 ) / 132396

= 236 / 561

= 236

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 236, 561, 231, 921 is 1
