Given numbers are 691, 690, 380, 555

The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 691, 690, 380, 555

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

Apply this formula for all numbers.

Step1:

LCM(691, 690) = 476790

GCD(691, 690) = ( 691 x 690 ) / 476790

= 691 / 690

= 691

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 691, 690, 380, 555 is 1
