Given numbers are 161, 440, 400, 668

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

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

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 161, 440, 400, 668

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

Apply this formula for all numbers.

Step1:

LCM(161, 440) = 70840

GCD(161, 440) = ( 161 x 440 ) / 70840

= 161 / 440

= 161

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 161, 440, 400, 668 is 1
