Given numbers are 820, 256, 626, 493

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

Apply this formula for all numbers.

Step1:

LCM(820, 256) = 52480

GCD(820, 256) = ( 820 x 256 ) / 52480

= 820 / 256

= 820

Step2:

LCM(4, 626) = 1252

GCD(4, 626) = ( 4 x 626 ) / 1252

= 4 / 626

= 4

Step3:

LCM(2, 493) = 986

GCD(2, 493) = ( 2 x 493 ) / 986

= 2 / 493

= 2

So, Greatest Common Divisor of 820, 256, 626, 493 is 1
