Given numbers are 755, 301, 778, 420

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 301 are 7 x 43

Prime factors of 778 are 2 x 389

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 755, 301, 778, 420

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

Apply this formula for all numbers.

Step1:

LCM(755, 301) = 227255

GCD(755, 301) = ( 755 x 301 ) / 227255

= 755 / 301

= 755

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 755, 301, 778, 420 is 1
