Given numbers are 804, 196, 636, 978

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

Apply this formula for all numbers.

Step1:

LCM(804, 196) = 39396

GCD(804, 196) = ( 804 x 196 ) / 39396

= 804 / 196

= 804

Step2:

LCM(4, 636) = 636

GCD(4, 636) = ( 4 x 636 ) / 636

= 4 / 636

= 4

Step3:

LCM(4, 978) = 1956

GCD(4, 978) = ( 4 x 978 ) / 1956

= 4 / 978

= 4

So, Greatest Common Divisor of 804, 196, 636, 978 is 2
