Given numbers are 989, 991, 587, 828

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

Apply this formula for all numbers.

Step1:

LCM(989, 991) = 980099

GCD(989, 991) = ( 989 x 991 ) / 980099

= 989 / 991

= 989

Step2:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 989, 991, 587, 828 is 1
