Given numbers are 785, 545, 261, 440

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

Apply this formula for all numbers.

Step1:

LCM(785, 545) = 85565

GCD(785, 545) = ( 785 x 545 ) / 85565

= 785 / 545

= 785

Step2:

LCM(5, 261) = 1305

GCD(5, 261) = ( 5 x 261 ) / 1305

= 5 / 261

= 5

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 785, 545, 261, 440 is 1
