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
