Given numbers are 611, 744, 820, 691

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

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

Prime factors of 691 are 691

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

Given numbers are 611, 744, 820, 691

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

Apply this formula for all numbers.

Step1:

LCM(611, 744) = 454584

GCD(611, 744) = ( 611 x 744 ) / 454584

= 611 / 744

= 611

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 611, 744, 820, 691 is 1
