Given numbers are 391, 697, 521, 200

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

Apply this formula for all numbers.

Step1:

LCM(391, 697) = 16031

GCD(391, 697) = ( 391 x 697 ) / 16031

= 391 / 697

= 391

Step2:

LCM(17, 521) = 8857

GCD(17, 521) = ( 17 x 521 ) / 8857

= 17 / 521

= 17

Step3:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

So, Greatest Common Divisor of 391, 697, 521, 200 is 1
