Given numbers are 283, 485, 451, 638

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

Apply this formula for all numbers.

Step1:

LCM(283, 485) = 137255

GCD(283, 485) = ( 283 x 485 ) / 137255

= 283 / 485

= 283

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 283, 485, 451, 638 is 1
