Given numbers are 487, 728, 691, 474

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

Apply this formula for all numbers.

Step1:

LCM(487, 728) = 354536

GCD(487, 728) = ( 487 x 728 ) / 354536

= 487 / 728

= 487

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 487, 728, 691, 474 is 1
