Given numbers are 645, 220, 575, 711

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

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

Prime factors of 575 are 5 x 5 x 23

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, 220, 575, 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, 220) = 28380

GCD(645, 220) = ( 645 x 220 ) / 28380

= 645 / 220

= 645

Step2:

LCM(5, 575) = 575

GCD(5, 575) = ( 5 x 575 ) / 575

= 5 / 575

= 5

Step3:

LCM(5, 711) = 3555

GCD(5, 711) = ( 5 x 711 ) / 3555

= 5 / 711

= 5

So, Greatest Common Divisor of 645, 220, 575, 711 is 1
