Given numbers are 830, 679, 179, 420

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 679 are 7 x 97

Prime factors of 179 are 179

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 830, 679, 179, 420

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

Apply this formula for all numbers.

Step1:

LCM(830, 679) = 563570

GCD(830, 679) = ( 830 x 679 ) / 563570

= 830 / 679

= 830

Step2:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 830, 679, 179, 420 is 1
