Given numbers are 422, 954, 243, 780

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 954 are 2 x 3 x 3 x 53

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 422, 954, 243, 780

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

Apply this formula for all numbers.

Step1:

LCM(422, 954) = 201294

GCD(422, 954) = ( 422 x 954 ) / 201294

= 422 / 954

= 422

Step2:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 422, 954, 243, 780 is 1
