Given numbers are 440, 411, 641, 691

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 411 are 3 x 137

Prime factors of 641 are 641

Prime factors of 691 are 691

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

Given numbers are 440, 411, 641, 691

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

Apply this formula for all numbers.

Step1:

LCM(440, 411) = 180840

GCD(440, 411) = ( 440 x 411 ) / 180840

= 440 / 411

= 440

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 691) = 691

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

= 1 / 691

= 1

So, Greatest Common Divisor of 440, 411, 641, 691 is 1
