Given numbers are 689, 570, 805, 782

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 805 are 5 x 7 x 23

Prime factors of 782 are 2 x 17 x 23

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

Given numbers are 689, 570, 805, 782

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

Apply this formula for all numbers.

Step1:

LCM(689, 570) = 392730

GCD(689, 570) = ( 689 x 570 ) / 392730

= 689 / 570

= 689

Step2:

LCM(1, 805) = 805

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

= 1 / 805

= 1

Step3:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

So, Greatest Common Divisor of 689, 570, 805, 782 is 1
