Given numbers are 820, 563, 755

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

Apply this formula for all numbers.

Step1:

LCM(820, 563) = 461660

GCD(820, 563) = ( 820 x 563 ) / 461660

= 820 / 563

= 820

Step2:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 820, 563, 755 is 1
