Given numbers are 838, 978, 168, 349

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

Apply this formula for all numbers.

Step1:

LCM(838, 978) = 409782

GCD(838, 978) = ( 838 x 978 ) / 409782

= 838 / 978

= 838

Step2:

LCM(2, 168) = 168

GCD(2, 168) = ( 2 x 168 ) / 168

= 2 / 168

= 2

Step3:

LCM(2, 349) = 698

GCD(2, 349) = ( 2 x 349 ) / 698

= 2 / 349

= 2

So, Greatest Common Divisor of 838, 978, 168, 349 is 1
