Given numbers are 687, 605, 232, 857

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

Apply this formula for all numbers.

Step1:

LCM(687, 605) = 415635

GCD(687, 605) = ( 687 x 605 ) / 415635

= 687 / 605

= 687

Step2:

LCM(1, 232) = 232

GCD(1, 232) = ( 1 x 232 ) / 232

= 1 / 232

= 1

Step3:

LCM(1, 857) = 857

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

= 1 / 857

= 1

So, Greatest Common Divisor of 687, 605, 232, 857 is 1
