Given numbers are 181, 640, 174, 407

The list of prime factors of all numbers are

Prime factors of 181 are 181

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 174 are 2 x 3 x 29

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 181, 640, 174, 407

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

Apply this formula for all numbers.

Step1:

LCM(181, 640) = 115840

GCD(181, 640) = ( 181 x 640 ) / 115840

= 181 / 640

= 181

Step2:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

Step3:

LCM(1, 407) = 407

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

= 1 / 407

= 1

So, Greatest Common Divisor of 181, 640, 174, 407 is 1
