The list of prime factors of all numbers are

Prime factors of 412 are 2 x 2 x 103

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 805 are 5 x 7 x 23

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 412, 688, 805, 972

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

Apply this formula for all numbers.

Step1:

LCM(412, 688) = 70864

GCD(412, 688) = ( 412 x 688 ) / 70864

= 412 / 688

= 412

Step2:

LCM(4, 805) = 3220

GCD(4, 805) = ( 4 x 805 ) / 3220

= 4 / 805

= 4

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 412, 688, 805, 972 is 1
