Given numbers are 820, 713, 81, 613

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

Apply this formula for all numbers.

Step1:

LCM(820, 713) = 584660

GCD(820, 713) = ( 820 x 713 ) / 584660

= 820 / 713

= 820

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 613) = 613

GCD(1, 613) = ( 1 x 613 ) / 613

= 1 / 613

= 1

So, Greatest Common Divisor of 820, 713, 81, 613 is 1
