Given numbers are 805, 977, 554, 221

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

Apply this formula for all numbers.

Step1:

LCM(805, 977) = 786485

GCD(805, 977) = ( 805 x 977 ) / 786485

= 805 / 977

= 805

Step2:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 805, 977, 554, 221 is 1
