Given numbers are 975, 978, 165, 104

The list of prime factors of all numbers are

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 978 are 2 x 3 x 163

Prime factors of 165 are 3 x 5 x 11

Prime factors of 104 are 2 x 2 x 2 x 13

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

Given numbers are 975, 978, 165, 104

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

Apply this formula for all numbers.

Step1:

LCM(975, 978) = 317850

GCD(975, 978) = ( 975 x 978 ) / 317850

= 975 / 978

= 975

Step2:

LCM(3, 165) = 165

GCD(3, 165) = ( 3 x 165 ) / 165

= 3 / 165

= 3

Step3:

LCM(3, 104) = 312

GCD(3, 104) = ( 3 x 104 ) / 312

= 3 / 104

= 3

So, Greatest Common Divisor of 975, 978, 165, 104 is 1
