Given numbers are 284, 355, 742, 386

The list of prime factors of all numbers are

Prime factors of 284 are 2 x 2 x 71

Prime factors of 355 are 5 x 71

Prime factors of 742 are 2 x 7 x 53

Prime factors of 386 are 2 x 193

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 284, 355, 742, 386

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

Apply this formula for all numbers.

Step1:

LCM(284, 355) = 1420

GCD(284, 355) = ( 284 x 355 ) / 1420

= 284 / 355

= 284

Step2:

LCM(71, 742) = 52682

GCD(71, 742) = ( 71 x 742 ) / 52682

= 71 / 742

= 71

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 284, 355, 742, 386 is 1
