Given numbers are 977, 869, 561, 181

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

Apply this formula for all numbers.

Step1:

LCM(977, 869) = 849013

GCD(977, 869) = ( 977 x 869 ) / 849013

= 977 / 869

= 977

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 977, 869, 561, 181 is 1
