Given numbers are 327, 755, 420, 117

The list of prime factors of all numbers are

Prime factors of 327 are 3 x 109

Prime factors of 755 are 5 x 151

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

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 327, 755, 420, 117

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

Apply this formula for all numbers.

Step1:

LCM(327, 755) = 246885

GCD(327, 755) = ( 327 x 755 ) / 246885

= 327 / 755

= 327

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 327, 755, 420, 117 is 1
