Given numbers are 728, 969, 991, 157

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

Apply this formula for all numbers.

Step1:

LCM(728, 969) = 705432

GCD(728, 969) = ( 728 x 969 ) / 705432

= 728 / 969

= 728

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 728, 969, 991, 157 is 1
