Given numbers are 180, 644, 841, 391

The list of prime factors of all numbers are

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 841 are 29 x 29

Prime factors of 391 are 17 x 23

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

Given numbers are 180, 644, 841, 391

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

Apply this formula for all numbers.

Step1:

LCM(180, 644) = 28980

GCD(180, 644) = ( 180 x 644 ) / 28980

= 180 / 644

= 180

Step2:

LCM(4, 841) = 3364

GCD(4, 841) = ( 4 x 841 ) / 3364

= 4 / 841

= 4

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 180, 644, 841, 391 is 1
