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

Apply this formula for all numbers.

Step1:

LCM(903, 873) = 262773

GCD(903, 873) = ( 903 x 873 ) / 262773

= 903 / 873

= 903

Step2:

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

= 3 / 840

= 3

Step3:

LCM(3, 978) = 978

GCD(3, 978) = ( 3 x 978 ) / 978

= 3 / 978

= 3

So, Greatest Common Divisor of 903, 873, 840, 978 is 3
