Given numbers are 645, 365, 823, 731

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

Apply this formula for all numbers.

Step1:

LCM(645, 365) = 47085

GCD(645, 365) = ( 645 x 365 ) / 47085

= 645 / 365

= 645

Step2:

LCM(5, 823) = 4115

GCD(5, 823) = ( 5 x 823 ) / 4115

= 5 / 823

= 5

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 645, 365, 823, 731 is 1
