Given numbers are 820, 395, 187, 725

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

Apply this formula for all numbers.

Step1:

LCM(820, 395) = 64780

GCD(820, 395) = ( 820 x 395 ) / 64780

= 820 / 395

= 820

Step2:

LCM(5, 187) = 935

GCD(5, 187) = ( 5 x 187 ) / 935

= 5 / 187

= 5

Step3:

LCM(1, 725) = 725

GCD(1, 725) = ( 1 x 725 ) / 725

= 1 / 725

= 1

So, Greatest Common Divisor of 820, 395, 187, 725 is 1
