Given numbers are 728, 890, 695, 188

The list of prime factors of all numbers are

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 890 are 2 x 5 x 89

Prime factors of 695 are 5 x 139

Prime factors of 188 are 2 x 2 x 47

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

Given numbers are 728, 890, 695, 188

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

Apply this formula for all numbers.

Step1:

LCM(728, 890) = 323960

GCD(728, 890) = ( 728 x 890 ) / 323960

= 728 / 890

= 728

Step2:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

Step3:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

So, Greatest Common Divisor of 728, 890, 695, 188 is 1
