Given numbers are 287, 854, 890, 438

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

Apply this formula for all numbers.

Step1:

LCM(287, 854) = 35014

GCD(287, 854) = ( 287 x 854 ) / 35014

= 287 / 854

= 287

Step2:

LCM(7, 890) = 6230

GCD(7, 890) = ( 7 x 890 ) / 6230

= 7 / 890

= 7

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 287, 854, 890, 438 is 1
