Given numbers are 855, 253, 644, 514

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 253 are 11 x 23

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 514 are 2 x 257

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

Given numbers are 855, 253, 644, 514

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

Apply this formula for all numbers.

Step1:

LCM(855, 253) = 216315

GCD(855, 253) = ( 855 x 253 ) / 216315

= 855 / 253

= 855

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 514) = 514

GCD(1, 514) = ( 1 x 514 ) / 514

= 1 / 514

= 1

So, Greatest Common Divisor of 855, 253, 644, 514 is 1
