Given numbers are 355, 430, 511, 857

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

Apply this formula for all numbers.

Step1:

LCM(355, 430) = 30530

GCD(355, 430) = ( 355 x 430 ) / 30530

= 355 / 430

= 355

Step2:

LCM(5, 511) = 2555

GCD(5, 511) = ( 5 x 511 ) / 2555

= 5 / 511

= 5

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 355, 430, 511, 857 is 1
