The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 665 are 5 x 7 x 19

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 945, 798, 665, 246

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

Apply this formula for all numbers.

Step1:

LCM(945, 798) = 35910

GCD(945, 798) = ( 945 x 798 ) / 35910

= 945 / 798

= 945

Step2:

LCM(21, 665) = 1995

GCD(21, 665) = ( 21 x 665 ) / 1995

= 21 / 665

= 21

Step3:

LCM(7, 246) = 1722

GCD(7, 246) = ( 7 x 246 ) / 1722

= 7 / 246

= 7

So, Greatest Common Divisor of 945, 798, 665, 246 is 1
