Given numbers are 405, 177, 667, 402

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 177 are 3 x 59

Prime factors of 667 are 23 x 29

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 405, 177, 667, 402

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

Apply this formula for all numbers.

Step1:

LCM(405, 177) = 23895

GCD(405, 177) = ( 405 x 177 ) / 23895

= 405 / 177

= 405

Step2:

LCM(3, 667) = 2001

GCD(3, 667) = ( 3 x 667 ) / 2001

= 3 / 667

= 3

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 405, 177, 667, 402 is 1
