Given numbers are 636, 420, 731, 805

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 731 are 17 x 43

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 636, 420, 731, 805

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

Apply this formula for all numbers.

Step1:

LCM(636, 420) = 22260

GCD(636, 420) = ( 636 x 420 ) / 22260

= 636 / 420

= 636

Step2:

LCM(12, 731) = 8772

GCD(12, 731) = ( 12 x 731 ) / 8772

= 12 / 731

= 12

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 636, 420, 731, 805 is 1
