Given numbers are 687, 425, 785, 242

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

Apply this formula for all numbers.

Step1:

LCM(687, 425) = 291975

GCD(687, 425) = ( 687 x 425 ) / 291975

= 687 / 425

= 687

Step2:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 687, 425, 785, 242 is 1
