Given numbers are 403, 689, 380, 611

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

Apply this formula for all numbers.

Step1:

LCM(403, 689) = 21359

GCD(403, 689) = ( 403 x 689 ) / 21359

= 403 / 689

= 403

Step2:

LCM(13, 380) = 4940

GCD(13, 380) = ( 13 x 380 ) / 4940

= 13 / 380

= 13

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 403, 689, 380, 611 is 1
