Given numbers are 178, 625, 840, 998

The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 998 are 2 x 499

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

Given numbers are 178, 625, 840, 998

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

Apply this formula for all numbers.

Step1:

LCM(178, 625) = 111250

GCD(178, 625) = ( 178 x 625 ) / 111250

= 178 / 625

= 178

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 178, 625, 840, 998 is 1
