Given numbers are 778, 130, 361, 257

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

Apply this formula for all numbers.

Step1:

LCM(778, 130) = 50570

GCD(778, 130) = ( 778 x 130 ) / 50570

= 778 / 130

= 778

Step2:

LCM(2, 361) = 722

GCD(2, 361) = ( 2 x 361 ) / 722

= 2 / 361

= 2

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 778, 130, 361, 257 is 1
