Given numbers are 520, 140, 693, 897

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 897 are 3 x 13 x 23

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

Given numbers are 520, 140, 693, 897

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

Apply this formula for all numbers.

Step1:

LCM(520, 140) = 3640

GCD(520, 140) = ( 520 x 140 ) / 3640

= 520 / 140

= 520

Step2:

LCM(20, 693) = 13860

GCD(20, 693) = ( 20 x 693 ) / 13860

= 20 / 693

= 20

Step3:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

So, Greatest Common Divisor of 520, 140, 693, 897 is 1
