Given numbers are 691, 472, 840, 407

The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 407 are 11 x 37

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

Given numbers are 691, 472, 840, 407

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

Apply this formula for all numbers.

Step1:

LCM(691, 472) = 326152

GCD(691, 472) = ( 691 x 472 ) / 326152

= 691 / 472

= 691

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 691, 472, 840, 407 is 1
