Given numbers are 690, 403, 272, 625

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 403 are 13 x 31

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

Prime factors of 625 are 5 x 5 x 5 x 5

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

Given numbers are 690, 403, 272, 625

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

Apply this formula for all numbers.

Step1:

LCM(690, 403) = 278070

GCD(690, 403) = ( 690 x 403 ) / 278070

= 690 / 403

= 690

Step2:

LCM(1, 272) = 272

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

= 1 / 272

= 1

Step3:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

So, Greatest Common Divisor of 690, 403, 272, 625 is 1
