Given numbers are 805, 390, 253, 497

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 253 are 11 x 23

Prime factors of 497 are 7 x 71

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

Given numbers are 805, 390, 253, 497

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

Apply this formula for all numbers.

Step1:

LCM(805, 390) = 62790

GCD(805, 390) = ( 805 x 390 ) / 62790

= 805 / 390

= 805

Step2:

LCM(5, 253) = 1265

GCD(5, 253) = ( 5 x 253 ) / 1265

= 5 / 253

= 5

Step3:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 805, 390, 253, 497 is 1
