Given numbers are 645, 869, 983, 788

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

Apply this formula for all numbers.

Step1:

LCM(645, 869) = 560505

GCD(645, 869) = ( 645 x 869 ) / 560505

= 645 / 869

= 645

Step2:

LCM(1, 983) = 983

GCD(1, 983) = ( 1 x 983 ) / 983

= 1 / 983

= 1

Step3:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

So, Greatest Common Divisor of 645, 869, 983, 788 is 1
