Given numbers are 991, 659, 466, 621

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

Apply this formula for all numbers.

Step1:

LCM(991, 659) = 653069

GCD(991, 659) = ( 991 x 659 ) / 653069

= 991 / 659

= 991

Step2:

LCM(1, 466) = 466

GCD(1, 466) = ( 1 x 466 ) / 466

= 1 / 466

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 991, 659, 466, 621 is 1
