Given numbers are 813, 788, 18, 853

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

Apply this formula for all numbers.

Step1:

LCM(813, 788) = 640644

GCD(813, 788) = ( 813 x 788 ) / 640644

= 813 / 788

= 813

Step2:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 813, 788, 18, 853 is 1
