Given numbers are 730, 861, 697, 945

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 861 are 3 x 7 x 41

Prime factors of 697 are 17 x 41

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

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

Given numbers are 730, 861, 697, 945

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

Apply this formula for all numbers.

Step1:

LCM(730, 861) = 628530

GCD(730, 861) = ( 730 x 861 ) / 628530

= 730 / 861

= 730

Step2:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 730, 861, 697, 945 is 1
