Given numbers are 830, 865, 937, 645

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 865 are 5 x 173

Prime factors of 937 are 937

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 830, 865, 937, 645

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

Apply this formula for all numbers.

Step1:

LCM(830, 865) = 143590

GCD(830, 865) = ( 830 x 865 ) / 143590

= 830 / 865

= 830

Step2:

LCM(5, 937) = 4685

GCD(5, 937) = ( 5 x 937 ) / 4685

= 5 / 937

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 830, 865, 937, 645 is 1
