Given numbers are 682, 803, 128, 257

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

Apply this formula for all numbers.

Step1:

LCM(682, 803) = 49786

GCD(682, 803) = ( 682 x 803 ) / 49786

= 682 / 803

= 682

Step2:

LCM(11, 128) = 1408

GCD(11, 128) = ( 11 x 128 ) / 1408

= 11 / 128

= 11

Step3:

LCM(1, 257) = 257

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

= 1 / 257

= 1

So, Greatest Common Divisor of 682, 803, 128, 257 is 1
