Given numbers are 821, 663, 502, 512

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

Apply this formula for all numbers.

Step1:

LCM(821, 663) = 544323

GCD(821, 663) = ( 821 x 663 ) / 544323

= 821 / 663

= 821

Step2:

LCM(1, 502) = 502

GCD(1, 502) = ( 1 x 502 ) / 502

= 1 / 502

= 1

Step3:

LCM(1, 512) = 512

GCD(1, 512) = ( 1 x 512 ) / 512

= 1 / 512

= 1

So, Greatest Common Divisor of 821, 663, 502, 512 is 1
