Given numbers are 897, 688, 890, 520

The list of prime factors of all numbers are

Prime factors of 897 are 3 x 13 x 23

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 890 are 2 x 5 x 89

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

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

Given numbers are 897, 688, 890, 520

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

Apply this formula for all numbers.

Step1:

LCM(897, 688) = 617136

GCD(897, 688) = ( 897 x 688 ) / 617136

= 897 / 688

= 897

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 897, 688, 890, 520 is 1
