Given numbers are 921, 279, 19, 869

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

Apply this formula for all numbers.

Step1:

LCM(921, 279) = 85653

GCD(921, 279) = ( 921 x 279 ) / 85653

= 921 / 279

= 921

Step2:

LCM(3, 19) = 57

GCD(3, 19) = ( 3 x 19 ) / 57

= 3 / 19

= 3

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 921, 279, 19, 869 is 1
