The list of prime factors of all numbers are

Prime factors of 571 are 571

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 571, 156, 765, 240

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

Apply this formula for all numbers.

Step1:

LCM(571, 156) = 89076

GCD(571, 156) = ( 571 x 156 ) / 89076

= 571 / 156

= 571

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 571, 156, 765, 240 is 1
