Given numbers are 120, 808, 389, 977

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

Apply this formula for all numbers.

Step1:

LCM(120, 808) = 12120

GCD(120, 808) = ( 120 x 808 ) / 12120

= 120 / 808

= 120

Step2:

LCM(8, 389) = 3112

GCD(8, 389) = ( 8 x 389 ) / 3112

= 8 / 389

= 8

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 120, 808, 389, 977 is 1
