Given numbers are 891, 712, 221, 788

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

Apply this formula for all numbers.

Step1:

LCM(891, 712) = 634392

GCD(891, 712) = ( 891 x 712 ) / 634392

= 891 / 712

= 891

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

So, Greatest Common Divisor of 891, 712, 221, 788 is 1
