Given numbers are 401, 644, 415, 274

The list of prime factors of all numbers are

Prime factors of 401 are 401

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

Prime factors of 415 are 5 x 83

Prime factors of 274 are 2 x 137

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

Given numbers are 401, 644, 415, 274

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

Apply this formula for all numbers.

Step1:

LCM(401, 644) = 258244

GCD(401, 644) = ( 401 x 644 ) / 258244

= 401 / 644

= 401

Step2:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

Step3:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1

So, Greatest Common Divisor of 401, 644, 415, 274 is 1
