Given numbers are 945, 535, 830, 689

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 535 are 5 x 107

Prime factors of 830 are 2 x 5 x 83

Prime factors of 689 are 13 x 53

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

Given numbers are 945, 535, 830, 689

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

Apply this formula for all numbers.

Step1:

LCM(945, 535) = 101115

GCD(945, 535) = ( 945 x 535 ) / 101115

= 945 / 535

= 945

Step2:

LCM(5, 830) = 830

GCD(5, 830) = ( 5 x 830 ) / 830

= 5 / 830

= 5

Step3:

LCM(5, 689) = 3445

GCD(5, 689) = ( 5 x 689 ) / 3445

= 5 / 689

= 5

So, Greatest Common Divisor of 945, 535, 830, 689 is 1
