Given numbers are 531, 643, 692, 455

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

Apply this formula for all numbers.

Step1:

LCM(531, 643) = 341433

GCD(531, 643) = ( 531 x 643 ) / 341433

= 531 / 643

= 531

Step2:

LCM(1, 692) = 692

GCD(1, 692) = ( 1 x 692 ) / 692

= 1 / 692

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 531, 643, 692, 455 is 1
