Given numbers are 149, 420, 838, 389

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

Apply this formula for all numbers.

Step1:

LCM(149, 420) = 62580

GCD(149, 420) = ( 149 x 420 ) / 62580

= 149 / 420

= 149

Step2:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 149, 420, 838, 389 is 1
