Given numbers are 257, 201, 163, 530

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

Apply this formula for all numbers.

Step1:

LCM(257, 201) = 51657

GCD(257, 201) = ( 257 x 201 ) / 51657

= 257 / 201

= 257

Step2:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 257, 201, 163, 530 is 1
