Given numbers are 253, 530, 549, 644

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 530 are 2 x 5 x 53

Prime factors of 549 are 3 x 3 x 61

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

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

Given numbers are 253, 530, 549, 644

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

Apply this formula for all numbers.

Step1:

LCM(253, 530) = 134090

GCD(253, 530) = ( 253 x 530 ) / 134090

= 253 / 530

= 253

Step2:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 253, 530, 549, 644 is 1
