Given numbers are 758, 178, 779, 420

The list of prime factors of all numbers are

Prime factors of 758 are 2 x 379

Prime factors of 178 are 2 x 89

Prime factors of 779 are 19 x 41

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 758, 178, 779, 420

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

Apply this formula for all numbers.

Step1:

LCM(758, 178) = 67462

GCD(758, 178) = ( 758 x 178 ) / 67462

= 758 / 178

= 758

Step2:

LCM(2, 779) = 1558

GCD(2, 779) = ( 2 x 779 ) / 1558

= 2 / 779

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 758, 178, 779, 420 is 1
