Given numbers are 257, 861, 509, 222

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

Apply this formula for all numbers.

Step1:

LCM(257, 861) = 221277

GCD(257, 861) = ( 257 x 861 ) / 221277

= 257 / 861

= 257

Step2:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 257, 861, 509, 222 is 1
