Given numbers are 978, 612, 491, 791

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 491 are 491

Prime factors of 791 are 7 x 113

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

Given numbers are 978, 612, 491, 791

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

Apply this formula for all numbers.

Step1:

LCM(978, 612) = 99756

GCD(978, 612) = ( 978 x 612 ) / 99756

= 978 / 612

= 978

Step2:

LCM(6, 491) = 2946

GCD(6, 491) = ( 6 x 491 ) / 2946

= 6 / 491

= 6

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 978, 612, 491, 791 is 1
