Given numbers are 458, 378, 642, 191

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

Apply this formula for all numbers.

Step1:

LCM(458, 378) = 86562

GCD(458, 378) = ( 458 x 378 ) / 86562

= 458 / 378

= 458

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 191) = 382

GCD(2, 191) = ( 2 x 191 ) / 382

= 2 / 191

= 2

So, Greatest Common Divisor of 458, 378, 642, 191 is 1
