Given numbers are 235, 640, 401, 698

The list of prime factors of all numbers are

Prime factors of 235 are 5 x 47

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

Prime factors of 401 are 401

Prime factors of 698 are 2 x 349

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

Given numbers are 235, 640, 401, 698

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

Apply this formula for all numbers.

Step1:

LCM(235, 640) = 30080

GCD(235, 640) = ( 235 x 640 ) / 30080

= 235 / 640

= 235

Step2:

LCM(5, 401) = 2005

GCD(5, 401) = ( 5 x 401 ) / 2005

= 5 / 401

= 5

Step3:

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

= 1 / 698

= 1

So, Greatest Common Divisor of 235, 640, 401, 698 is 1
