Given numbers are 689, 580, 603, 765

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 603 are 3 x 3 x 67

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 689, 580, 603, 765

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

Apply this formula for all numbers.

Step1:

LCM(689, 580) = 399620

GCD(689, 580) = ( 689 x 580 ) / 399620

= 689 / 580

= 689

Step2:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 689, 580, 603, 765 is 1
