Given numbers are 646, 785, 897, 612

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 785 are 5 x 157

Prime factors of 897 are 3 x 13 x 23

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 646, 785, 897, 612

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

Apply this formula for all numbers.

Step1:

LCM(646, 785) = 507110

GCD(646, 785) = ( 646 x 785 ) / 507110

= 646 / 785

= 646

Step2:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 646, 785, 897, 612 is 1
