Given numbers are 286, 397, 521, 921

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

Apply this formula for all numbers.

Step1:

LCM(286, 397) = 113542

GCD(286, 397) = ( 286 x 397 ) / 113542

= 286 / 397

= 286

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 286, 397, 521, 921 is 1
