Given numbers are 438, 569, 270, 765

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 569 are 569

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

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

Given numbers are 438, 569, 270, 765

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

Apply this formula for all numbers.

Step1:

LCM(438, 569) = 249222

GCD(438, 569) = ( 438 x 569 ) / 249222

= 438 / 569

= 438

Step2:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

Step3:

LCM(1, 765) = 765

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

= 1 / 765

= 1

So, Greatest Common Divisor of 438, 569, 270, 765 is 1
