Given numbers are 135, 805, 686, 406

The list of prime factors of all numbers are

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 805 are 5 x 7 x 23

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 135, 805, 686, 406

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

Apply this formula for all numbers.

Step1:

LCM(135, 805) = 21735

GCD(135, 805) = ( 135 x 805 ) / 21735

= 135 / 805

= 135

Step2:

LCM(5, 686) = 3430

GCD(5, 686) = ( 5 x 686 ) / 3430

= 5 / 686

= 5

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 135, 805, 686, 406 is 1
