Given numbers are 821, 656, 83, 404

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

Apply this formula for all numbers.

Step1:

LCM(821, 656) = 538576

GCD(821, 656) = ( 821 x 656 ) / 538576

= 821 / 656

= 821

Step2:

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

= 1 / 83

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 821, 656, 83, 404 is 1
