Given numbers are 830, 768, 682, 665

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 682 are 2 x 11 x 31

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 830, 768, 682, 665

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

Apply this formula for all numbers.

Step1:

LCM(830, 768) = 318720

GCD(830, 768) = ( 830 x 768 ) / 318720

= 830 / 768

= 830

Step2:

LCM(2, 682) = 682

GCD(2, 682) = ( 2 x 682 ) / 682

= 2 / 682

= 2

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 830, 768, 682, 665 is 1
