Given numbers are 425, 570, 988, 561

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

Apply this formula for all numbers.

Step1:

LCM(425, 570) = 48450

GCD(425, 570) = ( 425 x 570 ) / 48450

= 425 / 570

= 425

Step2:

LCM(5, 988) = 4940

GCD(5, 988) = ( 5 x 988 ) / 4940

= 5 / 988

= 5

Step3:

LCM(1, 561) = 561

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

= 1 / 561

= 1

So, Greatest Common Divisor of 425, 570, 988, 561 is 1
