Given numbers are 680, 670, 171, 779

The list of prime factors of all numbers are

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

Prime factors of 670 are 2 x 5 x 67

Prime factors of 171 are 3 x 3 x 19

Prime factors of 779 are 19 x 41

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

Given numbers are 680, 670, 171, 779

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

Apply this formula for all numbers.

Step1:

LCM(680, 670) = 45560

GCD(680, 670) = ( 680 x 670 ) / 45560

= 680 / 670

= 680

Step2:

LCM(10, 171) = 1710

GCD(10, 171) = ( 10 x 171 ) / 1710

= 10 / 171

= 10

Step3:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

So, Greatest Common Divisor of 680, 670, 171, 779 is 1
