Given numbers are 645, 654, 176, 711

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 654 are 2 x 3 x 109

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

Prime factors of 711 are 3 x 3 x 79

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

Given numbers are 645, 654, 176, 711

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

Apply this formula for all numbers.

Step1:

LCM(645, 654) = 140610

GCD(645, 654) = ( 645 x 654 ) / 140610

= 645 / 654

= 645

Step2:

LCM(3, 176) = 528

GCD(3, 176) = ( 3 x 176 ) / 528

= 3 / 176

= 3

Step3:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

So, Greatest Common Divisor of 645, 654, 176, 711 is 1
