Given numbers are 665, 390, 603, 175

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 603 are 3 x 3 x 67

Prime factors of 175 are 5 x 5 x 7

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

Given numbers are 665, 390, 603, 175

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

Apply this formula for all numbers.

Step1:

LCM(665, 390) = 51870

GCD(665, 390) = ( 665 x 390 ) / 51870

= 665 / 390

= 665

Step2:

LCM(5, 603) = 3015

GCD(5, 603) = ( 5 x 603 ) / 3015

= 5 / 603

= 5

Step3:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

So, Greatest Common Divisor of 665, 390, 603, 175 is 1
