Given numbers are 830, 643, 685, 111

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 643 are 643

Prime factors of 685 are 5 x 137

Prime factors of 111 are 3 x 37

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

Given numbers are 830, 643, 685, 111

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

Apply this formula for all numbers.

Step1:

LCM(830, 643) = 533690

GCD(830, 643) = ( 830 x 643 ) / 533690

= 830 / 643

= 830

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 830, 643, 685, 111 is 1
