Given numbers are 991, 156, 523, 629

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

Apply this formula for all numbers.

Step1:

LCM(991, 156) = 154596

GCD(991, 156) = ( 991 x 156 ) / 154596

= 991 / 156

= 991

Step2:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

Step3:

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

= 1 / 629

= 1

So, Greatest Common Divisor of 991, 156, 523, 629 is 1
