Given numbers are 581, 177, 765, 680

The list of prime factors of all numbers are

Prime factors of 581 are 7 x 83

Prime factors of 177 are 3 x 59

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

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 581, 177, 765, 680

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

Apply this formula for all numbers.

Step1:

LCM(581, 177) = 102837

GCD(581, 177) = ( 581 x 177 ) / 102837

= 581 / 177

= 581

Step2:

LCM(1, 765) = 765

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

= 1 / 765

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 581, 177, 765, 680 is 1
