Given numbers are 258, 387, 479, 388

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

Apply this formula for all numbers.

Step1:

LCM(258, 387) = 774

GCD(258, 387) = ( 258 x 387 ) / 774

= 258 / 387

= 258

Step2:

LCM(129, 479) = 61791

GCD(129, 479) = ( 129 x 479 ) / 61791

= 129 / 479

= 129

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 258, 387, 479, 388 is 1
