Given numbers are 258, 485, 325, 787

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

Apply this formula for all numbers.

Step1:

LCM(258, 485) = 125130

GCD(258, 485) = ( 258 x 485 ) / 125130

= 258 / 485

= 258

Step2:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 258, 485, 325, 787 is 1
