Given numbers are 434, 394, 145, 391

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

Apply this formula for all numbers.

Step1:

LCM(434, 394) = 85498

GCD(434, 394) = ( 434 x 394 ) / 85498

= 434 / 394

= 434

Step2:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 434, 394, 145, 391 is 1
