Given numbers are 995, 414, 668, 420

The list of prime factors of all numbers are

Prime factors of 995 are 5 x 199

Prime factors of 414 are 2 x 3 x 3 x 23

Prime factors of 668 are 2 x 2 x 167

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 995, 414, 668, 420

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

Apply this formula for all numbers.

Step1:

LCM(995, 414) = 411930

GCD(995, 414) = ( 995 x 414 ) / 411930

= 995 / 414

= 995

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 995, 414, 668, 420 is 1
