Given numbers are 670, 897, 285, 812

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 897 are 3 x 13 x 23

Prime factors of 285 are 3 x 5 x 19

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 670, 897, 285, 812

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

Apply this formula for all numbers.

Step1:

LCM(670, 897) = 600990

GCD(670, 897) = ( 670 x 897 ) / 600990

= 670 / 897

= 670

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 670, 897, 285, 812 is 1
