Given numbers are 805, 153, 358, 390

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 153 are 3 x 3 x 17

Prime factors of 358 are 2 x 179

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

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

Given numbers are 805, 153, 358, 390

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

Apply this formula for all numbers.

Step1:

LCM(805, 153) = 123165

GCD(805, 153) = ( 805 x 153 ) / 123165

= 805 / 153

= 805

Step2:

LCM(1, 358) = 358

GCD(1, 358) = ( 1 x 358 ) / 358

= 1 / 358

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 805, 153, 358, 390 is 1
