Given numbers are 283, 280, 460, 639

The list of prime factors of all numbers are

Prime factors of 283 are 283

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 283, 280, 460, 639

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

Apply this formula for all numbers.

Step1:

LCM(283, 280) = 79240

GCD(283, 280) = ( 283 x 280 ) / 79240

= 283 / 280

= 283

Step2:

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

= 1 / 460

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 283, 280, 460, 639 is 1
