Given numbers are 176, 744, 455, 643

The list of prime factors of all numbers are

Prime factors of 176 are 2 x 2 x 2 x 2 x 11

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 455 are 5 x 7 x 13

Prime factors of 643 are 643

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

Given numbers are 176, 744, 455, 643

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

Apply this formula for all numbers.

Step1:

LCM(176, 744) = 16368

GCD(176, 744) = ( 176 x 744 ) / 16368

= 176 / 744

= 176

Step2:

LCM(8, 455) = 3640

GCD(8, 455) = ( 8 x 455 ) / 3640

= 8 / 455

= 8

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 176, 744, 455, 643 is 1
