Given numbers are 388, 978, 353, 358

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

Apply this formula for all numbers.

Step1:

LCM(388, 978) = 189732

GCD(388, 978) = ( 388 x 978 ) / 189732

= 388 / 978

= 388

Step2:

LCM(2, 353) = 706

GCD(2, 353) = ( 2 x 353 ) / 706

= 2 / 353

= 2

Step3:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

So, Greatest Common Divisor of 388, 978, 353, 358 is 1
