Given numbers are 405, 496, 668, 946

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 496 are 2 x 2 x 2 x 2 x 31

Prime factors of 668 are 2 x 2 x 167

Prime factors of 946 are 2 x 11 x 43

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

Given numbers are 405, 496, 668, 946

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

Apply this formula for all numbers.

Step1:

LCM(405, 496) = 200880

GCD(405, 496) = ( 405 x 496 ) / 200880

= 405 / 496

= 405

Step2:

LCM(1, 668) = 668

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

= 1 / 668

= 1

Step3:

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

= 1 / 946

= 1

So, Greatest Common Divisor of 405, 496, 668, 946 is 1
