Given numbers are 646, 745, 511, 253

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 745 are 5 x 149

Prime factors of 511 are 7 x 73

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 646, 745, 511, 253

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

Apply this formula for all numbers.

Step1:

LCM(646, 745) = 481270

GCD(646, 745) = ( 646 x 745 ) / 481270

= 646 / 745

= 646

Step2:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 646, 745, 511, 253 is 1
