Given numbers are 392, 169, 644, 281

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

Apply this formula for all numbers.

Step1:

LCM(392, 169) = 66248

GCD(392, 169) = ( 392 x 169 ) / 66248

= 392 / 169

= 392

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 392, 169, 644, 281 is 1
