Given numbers are 420, 982, 772, 995

The list of prime factors of all numbers are

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

Prime factors of 982 are 2 x 491

Prime factors of 772 are 2 x 2 x 193

Prime factors of 995 are 5 x 199

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

Given numbers are 420, 982, 772, 995

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

Apply this formula for all numbers.

Step1:

LCM(420, 982) = 206220

GCD(420, 982) = ( 420 x 982 ) / 206220

= 420 / 982

= 420

Step2:

LCM(2, 772) = 772

GCD(2, 772) = ( 2 x 772 ) / 772

= 2 / 772

= 2

Step3:

LCM(2, 995) = 1990

GCD(2, 995) = ( 2 x 995 ) / 1990

= 2 / 995

= 2

So, Greatest Common Divisor of 420, 982, 772, 995 is 1
