Given numbers are 445, 417, 138, 246

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 417 are 3 x 139

Prime factors of 138 are 2 x 3 x 23

Prime factors of 246 are 2 x 3 x 41

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

Given numbers are 445, 417, 138, 246

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

Apply this formula for all numbers.

Step1:

LCM(445, 417) = 185565

GCD(445, 417) = ( 445 x 417 ) / 185565

= 445 / 417

= 445

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

So, Greatest Common Divisor of 445, 417, 138, 246 is 1
