Given numbers are 968, 221, 805, 691

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

Apply this formula for all numbers.

Step1:

LCM(968, 221) = 213928

GCD(968, 221) = ( 968 x 221 ) / 213928

= 968 / 221

= 968

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 968, 221, 805, 691 is 1
