Given numbers are 687, 731, 457, 346

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

Apply this formula for all numbers.

Step1:

LCM(687, 731) = 502197

GCD(687, 731) = ( 687 x 731 ) / 502197

= 687 / 731

= 687

Step2:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

Step3:

LCM(1, 346) = 346

GCD(1, 346) = ( 1 x 346 ) / 346

= 1 / 346

= 1

So, Greatest Common Divisor of 687, 731, 457, 346 is 1
