Given numbers are 998, 645, 805, 183

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

Apply this formula for all numbers.

Step1:

LCM(998, 645) = 643710

GCD(998, 645) = ( 998 x 645 ) / 643710

= 998 / 645

= 998

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 183) = 183

GCD(1, 183) = ( 1 x 183 ) / 183

= 1 / 183

= 1

So, Greatest Common Divisor of 998, 645, 805, 183 is 1
