Given numbers are 639, 252, 791, 248

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 791 are 7 x 113

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 639, 252, 791, 248

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

Apply this formula for all numbers.

Step1:

LCM(639, 252) = 17892

GCD(639, 252) = ( 639 x 252 ) / 17892

= 639 / 252

= 639

Step2:

LCM(9, 791) = 7119

GCD(9, 791) = ( 9 x 791 ) / 7119

= 9 / 791

= 9

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 639, 252, 791, 248 is 1
