Given numbers are 665, 504, 769, 161

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 769 are 769

Prime factors of 161 are 7 x 23

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

Given numbers are 665, 504, 769, 161

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

Apply this formula for all numbers.

Step1:

LCM(665, 504) = 47880

GCD(665, 504) = ( 665 x 504 ) / 47880

= 665 / 504

= 665

Step2:

LCM(7, 769) = 5383

GCD(7, 769) = ( 7 x 769 ) / 5383

= 7 / 769

= 7

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 665, 504, 769, 161 is 1
