Given numbers are 645, 996, 869, 764

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

Apply this formula for all numbers.

Step1:

LCM(645, 996) = 214140

GCD(645, 996) = ( 645 x 996 ) / 214140

= 645 / 996

= 645

Step2:

LCM(3, 869) = 2607

GCD(3, 869) = ( 3 x 869 ) / 2607

= 3 / 869

= 3

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 645, 996, 869, 764 is 1
