Given numbers are 661, 520, 175, 272

The list of prime factors of all numbers are

Prime factors of 661 are 661

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 175 are 5 x 5 x 7

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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

Given numbers are 661, 520, 175, 272

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

Apply this formula for all numbers.

Step1:

LCM(661, 520) = 343720

GCD(661, 520) = ( 661 x 520 ) / 343720

= 661 / 520

= 661

Step2:

LCM(1, 175) = 175

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

= 1 / 175

= 1

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 661, 520, 175, 272 is 1
