Given numbers are 556, 821, 861, 757

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

Apply this formula for all numbers.

Step1:

LCM(556, 821) = 456476

GCD(556, 821) = ( 556 x 821 ) / 456476

= 556 / 821

= 556

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

So, Greatest Common Divisor of 556, 821, 861, 757 is 1
