Given numbers are 178, 220, 856, 745

The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 745 are 5 x 149

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

Given numbers are 178, 220, 856, 745

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

Apply this formula for all numbers.

Step1:

LCM(178, 220) = 19580

GCD(178, 220) = ( 178 x 220 ) / 19580

= 178 / 220

= 178

Step2:

LCM(2, 856) = 856

GCD(2, 856) = ( 2 x 856 ) / 856

= 2 / 856

= 2

Step3:

LCM(2, 745) = 1490

GCD(2, 745) = ( 2 x 745 ) / 1490

= 2 / 745

= 2

So, Greatest Common Divisor of 178, 220, 856, 745 is 1
