Given numbers are 665, 290, 820, 716

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 290 are 2 x 5 x 29

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 716 are 2 x 2 x 179

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

Given numbers are 665, 290, 820, 716

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

Apply this formula for all numbers.

Step1:

LCM(665, 290) = 38570

GCD(665, 290) = ( 665 x 290 ) / 38570

= 665 / 290

= 665

Step2:

LCM(5, 820) = 820

GCD(5, 820) = ( 5 x 820 ) / 820

= 5 / 820

= 5

Step3:

LCM(5, 716) = 3580

GCD(5, 716) = ( 5 x 716 ) / 3580

= 5 / 716

= 5

So, Greatest Common Divisor of 665, 290, 820, 716 is 1
