Given numbers are 645, 726, 879, 495

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

Apply this formula for all numbers.

Step1:

LCM(645, 726) = 156090

GCD(645, 726) = ( 645 x 726 ) / 156090

= 645 / 726

= 645

Step2:

LCM(3, 879) = 879

GCD(3, 879) = ( 3 x 879 ) / 879

= 3 / 879

= 3

Step3:

LCM(3, 495) = 495

GCD(3, 495) = ( 3 x 495 ) / 495

= 3 / 495

= 3

So, Greatest Common Divisor of 645, 726, 879, 495 is 3
