Given numbers are 174, 660, 455, 816

The list of prime factors of all numbers are

Prime factors of 174 are 2 x 3 x 29

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 455 are 5 x 7 x 13

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 174, 660, 455, 816

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

Apply this formula for all numbers.

Step1:

LCM(174, 660) = 19140

GCD(174, 660) = ( 174 x 660 ) / 19140

= 174 / 660

= 174

Step2:

LCM(6, 455) = 2730

GCD(6, 455) = ( 6 x 455 ) / 2730

= 6 / 455

= 6

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 174, 660, 455, 816 is 1
