Given numbers are 178, 644, 358, 819

The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 358 are 2 x 179

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 178, 644, 358, 819

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

Apply this formula for all numbers.

Step1:

LCM(178, 644) = 57316

GCD(178, 644) = ( 178 x 644 ) / 57316

= 178 / 644

= 178

Step2:

LCM(2, 358) = 358

GCD(2, 358) = ( 2 x 358 ) / 358

= 2 / 358

= 2

Step3:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

So, Greatest Common Divisor of 178, 644, 358, 819 is 1
