Given numbers are 209, 893, 772, 665

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

Apply this formula for all numbers.

Step1:

LCM(209, 893) = 9823

GCD(209, 893) = ( 209 x 893 ) / 9823

= 209 / 893

= 209

Step2:

LCM(19, 772) = 14668

GCD(19, 772) = ( 19 x 772 ) / 14668

= 19 / 772

= 19

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 209, 893, 772, 665 is 1
