Given numbers are 865, 434, 270, 690

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 434 are 2 x 7 x 31

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

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 865, 434, 270, 690

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

Apply this formula for all numbers.

Step1:

LCM(865, 434) = 375410

GCD(865, 434) = ( 865 x 434 ) / 375410

= 865 / 434

= 865

Step2:

LCM(1, 270) = 270

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

= 1 / 270

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 865, 434, 270, 690 is 1
