Given numbers are 981, 891, 202, 511

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

Apply this formula for all numbers.

Step1:

LCM(981, 891) = 97119

GCD(981, 891) = ( 981 x 891 ) / 97119

= 981 / 891

= 981

Step2:

LCM(9, 202) = 1818

GCD(9, 202) = ( 9 x 202 ) / 1818

= 9 / 202

= 9

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 981, 891, 202, 511 is 1
