Given numbers are 405, 668, 961, 766

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 668 are 2 x 2 x 167

Prime factors of 961 are 31 x 31

Prime factors of 766 are 2 x 383

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

Given numbers are 405, 668, 961, 766

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

Apply this formula for all numbers.

Step1:

LCM(405, 668) = 270540

GCD(405, 668) = ( 405 x 668 ) / 270540

= 405 / 668

= 405

Step2:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 405, 668, 961, 766 is 1
