Given numbers are 945, 970, 809, 686

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 970 are 2 x 5 x 97

Prime factors of 809 are 809

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 945, 970, 809, 686

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

Apply this formula for all numbers.

Step1:

LCM(945, 970) = 183330

GCD(945, 970) = ( 945 x 970 ) / 183330

= 945 / 970

= 945

Step2:

LCM(5, 809) = 4045

GCD(5, 809) = ( 5 x 809 ) / 4045

= 5 / 809

= 5

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 945, 970, 809, 686 is 1
