Given numbers are 245, 674, 955, 420

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 674 are 2 x 337

Prime factors of 955 are 5 x 191

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 245, 674, 955, 420

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

Apply this formula for all numbers.

Step1:

LCM(245, 674) = 165130

GCD(245, 674) = ( 245 x 674 ) / 165130

= 245 / 674

= 245

Step2:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 245, 674, 955, 420 is 1
