Given numbers are 665, 860, 201, 389

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 201 are 3 x 67

Prime factors of 389 are 389

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

Given numbers are 665, 860, 201, 389

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

Apply this formula for all numbers.

Step1:

LCM(665, 860) = 114380

GCD(665, 860) = ( 665 x 860 ) / 114380

= 665 / 860

= 665

Step2:

LCM(5, 201) = 1005

GCD(5, 201) = ( 5 x 201 ) / 1005

= 5 / 201

= 5

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 665, 860, 201, 389 is 1
