Given numbers are 909, 885, 980, 788

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

Apply this formula for all numbers.

Step1:

LCM(909, 885) = 268155

GCD(909, 885) = ( 909 x 885 ) / 268155

= 909 / 885

= 909

Step2:

LCM(3, 980) = 2940

GCD(3, 980) = ( 3 x 980 ) / 2940

= 3 / 980

= 3

Step3:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

So, Greatest Common Divisor of 909, 885, 980, 788 is 1
