Given numbers are 861, 745, 712, 531

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

Apply this formula for all numbers.

Step1:

LCM(861, 745) = 641445

GCD(861, 745) = ( 861 x 745 ) / 641445

= 861 / 745

= 861

Step2:

LCM(1, 712) = 712

GCD(1, 712) = ( 1 x 712 ) / 712

= 1 / 712

= 1

Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

So, Greatest Common Divisor of 861, 745, 712, 531 is 1
