Given numbers are 204, 676, 836, 840

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

Apply this formula for all numbers.

Step1:

LCM(204, 676) = 34476

GCD(204, 676) = ( 204 x 676 ) / 34476

= 204 / 676

= 204

Step2:

LCM(4, 836) = 836

GCD(4, 836) = ( 4 x 836 ) / 836

= 4 / 836

= 4

Step3:

LCM(4, 840) = 840

GCD(4, 840) = ( 4 x 840 ) / 840

= 4 / 840

= 4

So, Greatest Common Divisor of 204, 676, 836, 840 is 4
