Given numbers are 221, 689, 154, 443

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

Apply this formula for all numbers.

Step1:

LCM(221, 689) = 11713

GCD(221, 689) = ( 221 x 689 ) / 11713

= 221 / 689

= 221

Step2:

LCM(13, 154) = 2002

GCD(13, 154) = ( 13 x 154 ) / 2002

= 13 / 154

= 13

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 221, 689, 154, 443 is 1
