Given numbers are 116, 972, 840, 389

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

Apply this formula for all numbers.

Step1:

LCM(116, 972) = 28188

GCD(116, 972) = ( 116 x 972 ) / 28188

= 116 / 972

= 116

Step2:

LCM(4, 840) = 840

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

= 4 / 840

= 4

Step3:

LCM(4, 389) = 1556

GCD(4, 389) = ( 4 x 389 ) / 1556

= 4 / 389

= 4

So, Greatest Common Divisor of 116, 972, 840, 389 is 1
