Given numbers are 897, 690, 715, 422

The list of prime factors of all numbers are

Prime factors of 897 are 3 x 13 x 23

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

Prime factors of 715 are 5 x 11 x 13

Prime factors of 422 are 2 x 211

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

Given numbers are 897, 690, 715, 422

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

Apply this formula for all numbers.

Step1:

LCM(897, 690) = 8970

GCD(897, 690) = ( 897 x 690 ) / 8970

= 897 / 690

= 897

Step2:

LCM(69, 715) = 49335

GCD(69, 715) = ( 69 x 715 ) / 49335

= 69 / 715

= 69

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 897, 690, 715, 422 is 1
