Given numbers are 821, 279, 681, 452

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

Apply this formula for all numbers.

Step1:

LCM(821, 279) = 229059

GCD(821, 279) = ( 821 x 279 ) / 229059

= 821 / 279

= 821

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

So, Greatest Common Divisor of 821, 279, 681, 452 is 1
