Given numbers are 854, 638, 624, 253

The list of prime factors of all numbers are

Prime factors of 854 are 2 x 7 x 61

Prime factors of 638 are 2 x 11 x 29

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 253 are 11 x 23

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

Given numbers are 854, 638, 624, 253

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

Apply this formula for all numbers.

Step1:

LCM(854, 638) = 272426

GCD(854, 638) = ( 854 x 638 ) / 272426

= 854 / 638

= 854

Step2:

LCM(2, 624) = 624

GCD(2, 624) = ( 2 x 624 ) / 624

= 2 / 624

= 2

Step3:

LCM(2, 253) = 506

GCD(2, 253) = ( 2 x 253 ) / 506

= 2 / 253

= 2

So, Greatest Common Divisor of 854, 638, 624, 253 is 1
