Given numbers are 645, 122, 691, 884

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

Apply this formula for all numbers.

Step1:

LCM(645, 122) = 78690

GCD(645, 122) = ( 645 x 122 ) / 78690

= 645 / 122

= 645

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

So, Greatest Common Divisor of 645, 122, 691, 884 is 1
