Given numbers are 551, 257, 440, 775

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

Apply this formula for all numbers.

Step1:

LCM(551, 257) = 141607

GCD(551, 257) = ( 551 x 257 ) / 141607

= 551 / 257

= 551

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 551, 257, 440, 775 is 1
