Given numbers are 265, 252, 403, 990

The list of prime factors of all numbers are

Prime factors of 265 are 5 x 53

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

Prime factors of 403 are 13 x 31

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 265, 252, 403, 990

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

Apply this formula for all numbers.

Step1:

LCM(265, 252) = 66780

GCD(265, 252) = ( 265 x 252 ) / 66780

= 265 / 252

= 265

Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 265, 252, 403, 990 is 1
